FIELD

Provided herein are bioluminescent polypeptides and compositions and methods for the assembly of tripartite or multipartite bioluminescent complexes. In particular embodiments, a bioluminescent complex is formed upon the interaction of three or more peptide and/or polypeptide components.

BACKGROUND

Biological processes and analyte detection rely on the co-localization and interactions between molecules, macromolecules, and molecular complexes. In order to understand such processes, and to develop techniques and compounds to manipulate them for research, clinical, and other practical applications, it is necessary to have tools available to detect and monitor these co-localizations/interactions. The study of these interactions, particularly under physiological conditions (e.g., at normal expression levels for monitoring protein interactions) or in complex sample matrices (e.g. blood samples, environmental samples), requires high sensitivity.

SUMMARY

Provided herein are bioluminescent polypeptides and compositions and methods for the assembly of a tripartite or multipartite bioluminescent complex. In particular embodiments, a bioluminescent complex is formed upon the interaction of three or more peptide and/or polypeptide components.

Experiments conducted during development of embodiments herein demonstrate the assembly of a bioluminescent complex, capable of generating luminescence in the presence of an appropriate substrate (e.g., a coelenterazine or a coelenterazine analog substrate), from complementary polypeptide(s) and peptide(s) that collectively span the the length (or >75% of the length, >80% of the length, >85% of the length, >90% of the length, >95% of the length, or more) of a luciferase base sequence (or collectively comprise at least 40% sequence identity to a luciferase base sequence (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75% >80%, >85%, >90%, >95%, or more). In some embodiments, “complementary” polyptpide(s) and peptide(s) are separate molecules that each correspond to a portion of a luciferase base sequence. Through structural complementarity, they assemble to form a bioluminescent complex.

Additional experiments were conducted during development of embodiments herein to develop monomeric bioluminescent polypeptides with enhanced characteristics (e.g., stability, luminescence, etc.).

In some embodiments, the complementary polypeptide(s) and peptide(s) are fragments of a luciferase base sequence that assemble to form a bioluminescent complex. In some embodiments, the fragments collectively comprise the full length of the luciferase base sequence. In some embodiments, the fragments collectively comprise at least 75% of the full length of the luciferase base sequence (e.g., >75% of the length, >80% of the length, >85% of the length, >90% of the length, >95% of the length, or more).

In some embodiments, the complementary polypeptide(s) and peptide(s) are variants of portions of a luciferase base sequence individually comprising at least 40% sequence identity to the corresponding portion of the luciferase base sequence (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75% >80%, >85%, >90%, >95%, or more) that assemble to form a bioluminescent complex. In some embodiments, the complementary polypeptide(s) and peptide(s) are variants of portions of a luciferase base sequence collectively comprising at least 40% sequence identity to the entire luciferase base sequence (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75% >80%, >85%, >90%, >95%, or more) that assemble to form a bioluminescent complex. In some embodiments, the fragments collectively comprise the full length of the luciferase base sequence. In some embodiments, the complementary polypeptide(s) and peptide(s) collectively comprise at least 75% of the full length of the luciferase base sequence (e.g., >75% of the length, >80% of the length, >85% of the length, >90% of the length, >95% of the length, or more).

Examples of luciferase base sequences include SEQ ID NO: 1, SEQ ID NO: 3, SEQ ID NO: 788, and SEQ ID NO: 789.

For example, if a luciferase base sequence is 170 amino acid residues in length, an exemplary polypeptide component may be, for example 102, 124, 133, or 148 amino acids in length, and 1, 2, 3, 4, 5, or more complementary peptides correspond to the remaining 68, 46, 37, or 22 amino acids.

FIG. 153. Translocation assay. POI is endogenously tagged with HiBiT. Upon stimulation, the POI translocates to a different cellular compartment, for example the nucleus. A LgBiT-nuclear sensor could be used to detect this translocation event as the HiBiT meets LgBiT resulting in luminescence signal.

FIG. 154. Membrane translocation assay with wild-type LgBiT sensor. PKCα-HiBiT cell line was transfected with wild-type LgBiT-membrane sensor. Due to the strong interaction between LgBiT and HiBiT, the spontaneous complementation occurs, leading to no response to PMA stimuli.

FIG. 155. Membrane translocation assay with LgBiT* sensor (SEQ ID NO: 979). PKCα-HiBiT cell line was transfected with different amount of DNA encoding LgBiT*-membrane sensor. Upon PMA treatment, PKCα-HiBiT migrates to the plasma membrane, where the LgBiT*-membrane sensor anchors. The assembly between HiBiT and LgBiT* produces luminescence signal, and the signal is proportional to the amount of PKCα-HiBiT on the membrane. The assay is sensitive and robust. Titration of PMA yielded similar EC₅₀ (EC₅₀=2.0 nM) regardless of the amount of sensor input. Fold response is varied between 12- to 19-fold depending on the amount of sensor input.

FIG. 156. Nuclear translocation assay with LgBiT* sensor. p65-HiBiT cell line was transfected with DNA encoding LgBiT*-nuclear sensor. Addition of TNFα recruits p65 to the nucleus where LgBiT*-nuclear sensor localizes. Complementation occurs between HiBiT and LgBiT* to produce light. The signal intensity reflects the concentration of p65 in the nucleus. Titration of TNFα yielded EC₅₀ of 0.7 ng/mL with fold-response of 4. Real-time measurement showed that it requires 30 min to reach the maximum accumulation of p65 in the nucleus upon stimulation.

Transfected cells were treated with phorbol-12-myristate-13 acetate (PMA) and measured kinetically. All 3 membrane sensors resulted in similar EC₅₀, suggesting the affinity of LgBiT variants to HiBiT do not effect translocation events of PKCα.

FIG. 226. Membrane/HaloTag®-LgBiT sensor—mammalian cell expression and luinescence assays. Reversibility of HiBiT-LgBiT* complex. Increased PMA concentration recruits more PKCα to the plasma membrane, resulting in higher luminescence signal, as more PKCα-HiBiT complementing with LgBiT* membrane sensor. Conversely, less PKCα accumulates in the cytosol; thus, decreasing luminescence signal as pairing with HaloTag®-LgBiT (cytosolic sensor).

FIG. 227. Translocation event of PKCα. Kinetic measurement of PKCα translocation event. Accumulation of PKCα to the plasma membrane can be measured kinetically, when paired with membrane sensor. Under PMA stimulation, PKCα reaches its maximum accumulation to the plasma membrane at t=16 min.

DEFINITIONS

Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments described herein, some preferred methods, compositions, devices, and materials are described herein. However, before the present materials and methods are described, it is to be understood that this invention is not limited to the particular molecules, compositions, methodologies or protocols herein described, as these may vary in accordance with routine experimentation and optimization. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope of the embodiments described herein.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. However, in case of conflict, the present specification, including definitions, will control. Accordingly, in the context of the embodiments described herein, the following definitions apply.

As used herein and in the appended claims, the singular forms “a”, “an” and “the” include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to “a peptide” is a reference to one or more peptides and equivalents thereof known to those skilled in the art, and so forth.

As used herein, the term “and/or” includes any and all combinations of listed items, including any of the listed items individually. For example, “A, B, and/or C” encompasses A, B, C, AB, AC, BC, and ABC, each of which is to be considered separately described by the statement “A, B, and/or C.”

As used herein, the term “comprise” and linguistic variations thereof denote the presence of recited feature(s), element(s), method step(s), etc. without the exclusion of the presence of additional feature(s), element(s), method step(s), etc. Conversely, the term “consisting of” and linguistic variations thereof, denotes the presence of recited feature(s), element(s), method step(s), etc. and excludes any unrecited feature(s), element(s), method step(s), etc., except for ordinarily-associated impurities. The phrase “consisting essentially of” denotes the recited feature(s), element(s), method step(s), etc. and any additional feature(s), element(s), method step(s), etc. that do not materially affect the basic nature of the composition, system, or method. Many embodiments herein are described using open “comprising” language. Such embodiments encompass multiple closed “consisting of” and/or “consisting essentially of” embodiments, which may alternatively be claimed or described using such language.

As used herein, the term “substantially” means that the recited characteristic, parameter, and/or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide. A characteristic or feature that is substantially absent (e.g., substantially non-luminescent) may be one that is within the noise, beneath background, below the detection capabilities of the assay being used, or a small fraction (e.g., <1%, <0.1%, <0.01%, <0.001%, <0.00001%, <0.000001%, <0.0000001%) of the significant characteristic (e.g., luminescent intensity of a bioluminescent protein or bioluminescent complex).

As used herein, the term “bioluminescence” refers to production and emission of light by a chemical reaction catalyzed by, or enabled by, an enzyme, protein, protein complex, or other biomolecule (e.g., bioluminescent complex). In typical embodiments, a substrate for a bioluminescent entity (e.g., bioluminescent protein or bioluminescent complex) is converted into an unstable form by the bioluminescent entity; the substrate subsequently emits light.

As used herein the term “complementary” refers to the characteristic of two or more structural elements (e.g., peptide, polypeptide, nucleic acid, small molecule, etc.) of being able to hybridize, dimerize, or otherwise form a complex with each other. For example, a “complementary peptide and polypeptide” are capable of coming together to form a complex. Complementary elements may require assistance (facilitation) to form a complex (e.g., from interaction elements), for example, to place the elements in the proper conformation for complementarity, to place the elements in the proper proximity for complementarity, to co-localize complementary elements, to lower interaction energy for complementary, to overcome insufficient affinity for one another, etc.

As used herein, the term “complex” refers to an assemblage or aggregate of molecules (e.g., peptides, polypeptides, etc.) in direct and/or indirect contact with one another. In one aspect, “contact,” or more particularly, “direct contact” means two or more molecules are close enough so that attractive noncovalent interactions, such as Van der Waal forces, hydrogen bonding, ionic and hydrophobic interactions, and the like, dominate the interaction of the molecules. In such an aspect, a complex of molecules (e.g., peptides and polypeptide) is formed under assay conditions such that the complex is thermodynamically favored (e.g., compared to a non-aggregated, or non-complexed, state of its component molecules). As used herein the term “complex,” unless described as otherwise, refers to the assemblage of two or more molecules (e.g., peptides, polypeptides or a combination thereof).

As used herein, the term “non-luminescent” refers to an entity (e.g., peptide, polypeptide, complex, protein, etc.) that exhibits the characteristic of not emitting a detectable amount of light in the visible spectrum (e.g., in the presence of a substrate). For example, an entity may be referred to as non-luminescent if it does not exhibit detectable luminescence in a given assay. As used herein, the term “non-luminescent” is synonymous with the term “substantially non-luminescent. In some embodiments, an entity is considered “non-luminescent” if any light emission is sufficiently minimal so as not to create interfering background for a particular assay.

As used herein, the terms “non-luminescent peptide” and “non-luminescent polypeptide” refer to peptides and polypeptides that exhibit substantially no luminescence (e.g., in the presence of a substrate), or an amount that is beneath the noise (e.g., 100-fold, 200-fold, 500-fold, 1×10³-fold, 1×10⁴-fold, 1×10⁵-fold, 1×10⁶-fold, 1×10⁷-fold, etc.) when compared to a significant signal (e.g., a bioluminescent complex) under standard conditions (e.g., physiological conditions, assay conditions, etc.) and with typical instrumentation (e.g., luminometer, etc.). In some embodiments, such non-luminescent peptides and polypeptides assemble, according to the criteria described herein, to form a bioluminescent complex.

As used herein, the term “interaction element” refers to a moiety that assists or facilitates the bringing together of non-luminescent elements to form a bioluminescent complex. In some embodiments, a pair of interaction elements (a.k.a. “interaction pair”) is attached to a pair of non-luminescent elements (e.g., non-luminescent peptides), and the attractive interaction between the two interaction elements facilitates formation of the bioluminescent complex; although the present invention is not limited to such a mechanism, and an understanding of the mechanism is not required to practice the invention. Interaction elements may facilitate formation of the bioluminescent complex by any suitable mechanism (e.g., bringing non-luminescent elements into close proximity, placing a non-luminescent element in proper conformation for stable interaction, reducing activation energy for complex formation, combinations thereof, etc.). An interaction element may be a protein, polypeptide, peptide, small molecule, cofactor, nucleic acid, lipid, carbohydrate, antibody, etc. An interaction pair may be made of two of the same interaction elements (i.e., homopair) or two different interaction elements (i.e., heteropair). In the case of a heteropair, the interaction elements may be the same type of moiety (e.g., polypeptides) or may be two different types of moieties (e.g., polypeptide and small molecule). In some embodiments, in which complex formation by the interaction pair is studied, an interaction pair may be referred to as a “target pair” or a “pair of interest,” and the individual interaction elements are referred to as “target elements” (e.g., “target peptide,” “target polypeptide,” etc.) or “elements of interest” (e.g., “peptide of interest,” “polypeptide or interest,” etc.).

As used herein, the term “low affinity” describes an intermolecular interaction between two or more (e.g., three) entities that is too weak to result in significant complex formation between the entities, except at concentrations substantially higher (e.g., 2-fold, 5-fold, 10-fold, 100-fold, 1000-fold, or more) than physiologic or assay conditions, or with facilitation from the formation of a second complex of attached elements (e.g., interaction elements).

As used herein, the term “high affinity” describes an intermolecular interaction between two or more (e.g., three) entities that is of sufficient strength to produce detectable complex formation under physiologic or assay conditions, without facilitation from the formation of a second complex of attached elements (e.g., interaction elements).

As used herein, the term “co-localization element” refers to a moiety that facilitates co-localization of non-luminescent elements. In some embodiments, a set of non-luminescent elements has sufficient affinity to form a complex when the non-luminescent elements are co-localized at sufficient concentration. In such embodiments, a set (e.g., pair) of co-localization elements (a.k.a. “co-localization pair”) is attached to a pair of non-luminescent elements (e.g., non-luminescent peptides), and the co-localization (e.g., within a cellular compartment, within a tissue, within a solution, on a solid matrix support, etc.) of the two co-localization elements facilitates co-localization of the non-luminescent elements, thereby facilitating formation of the bioluminescent complex; although the present invention is not limited to such a mechanism, and an understanding of the mechanism is not required to practice the invention. In some embodiments, due to the capacity of the non-luminescent elements to self-assemble into a luminescent complex, the co-localization elements need not directly interact to facilitate complex formation. A co-localization element may be a protein, polypeptide, peptide, small molecule, cofactor, nucleic acid, lipid, carbohydrate, antibody, etc. A co-localization pair may be made of two of the same co-localization elements (i.e., homopair) or two different co-localization elements (i.e., heteropair). In the case of a heteropair, the co-localization elements may be the same type of moiety (e.g., polypeptides) or may be two different types of moieties (e.g., polypeptide and small molecule). In some embodiments, in which the localization of the co-localization pair is studied, a co-localization pair may be referred to as a “target pair” or a “pair of interest,” and the individual co-localization elements are referred to as “target elements” (e.g., “target peptide,” “target polypeptide,” etc.) or “elements of interest” (e.g., “peptide of interest,” “polypeptide or interest,” etc.).

As used herein, the term “coelenterazine” refers to naturally-occurring (“native”) coelenterazine. As used herein, the term “coelenterazine analog” or “coelenterazine derivative” refers to synthetic (e.g., derivative or variant) and natural analogs thereof, including furimazine, coelenterazine-n, coelenterazine-f, coelenterazine-h, coelenterazine-hcp, coelenterazine-cp, coelenterazine-c, coelenterazine-e, coelenterazine-fcp, bis-deoxycoelenterazine (“coelenterazine-hh”), coelenterazine-i, coelenterazine-icp, coelenterazine-v, and 2-methyl coelenterazine, in addition to those disclosed in WO 2003/040100; U.S. application Ser. No. 12/056,073 (paragraph [0086]); U.S. Pat. No. 8,669,103; WO 2012/061529, U.S. Pat. Pub. 2017/0233789 and U.S. Pat. Pub. 2018/0030059; the disclosures of which are incorporated by reference herein in their entireties. In some embodiments, coelenterazine analogs include pro-substrates such as, for example, those described in U.S. application Ser. No. 12/056,073; U.S. Pub. No. 2012/0707849; U.S. Pub. No. 2014/0099654; herein incorporated by reference in their entireties.

As used herein, the term “preexisting protein” refers to an amino acid sequence that was in physical existence prior to a certain event or date. A “peptide that is not a fragment of a preexisting protein” is a short amino acid chain that is not a fragment or sub-sequence of a protein (e.g., synthetic or naturally-occurring) that was in physical existence prior to the design and/or synthesis of the peptide.

As used herein, the term “fragment” refers to a peptide or polypeptide that results from dissection or “fragmentation” of a larger whole entity (e.g., protein, polypeptide, enzyme, etc.), or a peptide or polypeptide prepared to have the same sequence as such. Therefore, a fragment is a subsequence of the whole entity (e.g., protein, polypeptide, enzyme, etc.) from which it is made and/or designed. A peptide or polypeptide that is not a subsequence of a preexisting whole protein is not a fragment (e.g., not a fragment of a preexisting protein). A peptide or polypeptide that is “not a fragment of a preexisting bioluminescent protein” is an amino acid chain that is not a subsequence of a protein (e.g., natural or synthetic) that: (1) was in physical existence prior to design and/or synthesis of the peptide or polypeptide, and (2) exhibits substantial bioluminescent activity.

As used herein, the term “subsequence” refers to peptide or polypeptide that has 100% sequence identify with a portion of another, larger peptide or polypeptide. The subsequence is a perfect sequence match for a portion of the larger amino acid chain.

The term “amino acid” refers to natural amino acids, unnatural amino acids, and amino acid analogs, all in their D and L stereoisomers, unless otherwise indicated, if their structures allow such stereoisomeric forms.

Natural amino acids include alanine (Ala or A), arginine (Arg or R), asparagine (Asn or N), aspartic acid (Asp or D), cysteine (Cys or C), glutamine (Gln or Q), glutamic acid (Glu or E), glycine (Gly or G), histidine (His or H), isoleucine (Ile or I), leucine (Leu or L), Lysine (Lys or K), methionine (Met or M), phenylalanine (Phe or F), proline (Pro or P), serine (Ser or S), threonine (Thr or T), tryptophan (Trp or W), tyrosine (Tyr or Y) and valine (Val or V).

Unnatural reactive amino acids are described in, for example, Boutureira, O. and G. J. Bernardes (2015) “Advances in chemical protein modification.” Chem Rev 115(5): 2174-2195; herein incorporated by reference in its entirety.

The term “amino acid analog” refers to a natural or unnatural amino acid where one or more of the C-terminal carboxy group, the N-terminal amino group and side-chain bioactive group has been chemically blocked, reversibly or irreversibly, or otherwise modified to another bioactive group. For example, aspartic acid-(beta-methyl ester) is an amino acid analog of aspartic acid; N-ethylglycine is an amino acid analog of glycine; or alanine carboxamide is an amino acid analog of alanine. Other amino acid analogs include methionine sulfoxide, methionine sulfone, S-(carboxymethyl)-cysteine, S-(carboxymethyl)-cysteine sulfoxide and S-(carboxymethyl)-cysteine sulfone. Amino acid analogs may comprise amino acids with various protecting groups (Isidro-Llobet, A., et al. (2009). “Amino Acid-Protecting Groups.” Chemical Reviews 109(6): 2455-2504; herein incorporated by reference in its entirety).

As used herein, unless otherwise specified, the terms “peptide” and “polypeptide” refer to polymer compounds of two or more amino acids joined through the main chain by peptide amide bonds (—C(O)NH—). The term “peptide” typically refers to short amino acid polymers (e.g., chains having fewer than 30 amino acids), whereas the term “polypeptide” typically refers to longer amino acid polymers (e.g., chains having more than 30 amino acids).

As used herein, unless otherwise specified, the term “dipeptide” refers to a peptide or small polypeptide (e.g., <70 amino acids, <60 amino acids, <50 amino acids, etc.) comprising two peptide segments (e.g., corresponding to two beta strands of a luciferase (e.g., a “β9/β10 dipeptide,” corresponding to the β9 and β10 strands of an OgLuc luciferase polypeptide), fused/attached diretly or indirectly (e.g., via a linker (e.g., peptide linker (e.g., 1-10 amino acids (e.g., a single glycine)))).

As used herein, unless otherwise specified, the term “tripeptide” refers to a peptide or small polypeptide (e.g., <100 amino acids, <90 amino acids, <80 amino acids, etc.) comprising three peptide segments (e.g., corresponding to three beta strands of a luciferase (e.g., a “β8-10 tripeptide,” corresponding to the β8-10 strands of an OgLuc luciferase polypeptide), fused/attached diretly or indirectly (e.g., via a linker (e.g., peptide linker (e.g., 1-10 amino acids (e.g., a single glycine)))).

As used herein, terms “peptidomimetic” and “peptide mimetic” refer to peptide-like or polypeptide-like molecules that emulate a sequence derived from a protein or peptide. A peptidomimetic may contain amino acids analogs, peptoid amino acids, and/or non-amino acid components either exclusively or in combination with amino acids (e.g., natural or non-natural amino acids). Examples of peptidomimitecs include chemically modified peptides/polypeptides, peptoids (side chains are appended to the nitrogen atom of the peptide backbone rather than to the α-carbons), β-peptides (amino group bonded to the β carbon rather than the α carbon), etc.

As used herein, the term “peptoid” refers to a class of peptidomimetics where the side chains are functionalized on the nitrogen atom of the peptide backbone rather than to the α-carbon.

As used herein, the term “artificial” refers to compositions and systems that are designed or prepared by man and are not naturally occurring. For example, an artificial peptide, peptoid, or nucleic acid is one comprising a non-natural sequence (e.g., a peptide without 100% identity with a naturally-occurring protein or a fragment thereof).

As used herein, a “conservative” amino acid substitution refers to the substitution of an amino acid in a peptide or polypeptide with another amino acid having similar chemical properties such as size or charge. For purposes of the present disclosure, each of the following eight groups contains amino acids that are conservative substitutions for one another:

1) Alanine (A) and Glycine (G);

2) Aspartic acid (D) and Glutamic acid (E);

3) Asparagine (N) and Glutamine (Q);

4) Arginine (R) and Lysine (K);

5) Isoleucine (I), Leucine (L), Methionine (M), and Valine (V);

6) Phenylalanine (F), Tyrosine (Y), and Tryptophan (W);

7) Serine (S) and Threonine (T); and

8) Cysteine (C) and Methionine (M).

Naturally occurring residues may be divided into classes based on common side chain properties, for example: polar positive (or basic) (histidine (H), lysine (K), and arginine (R)); polar negative (or acidic) (aspartic acid (D), glutamic acid (E)); polar neutral (serine (S), threonine (T), asparagine (N), glutamine (Q)); non-polar aliphatic (alanine (A), valine (V), leucine (L), isoleucine (I), methionine (M)); non-polar aromatic (phenylalanine (F), tyrosine (Y), tryptophan (W)); proline and glycine; and cysteine. As used herein, a “semi-conservative” amino acid substitution refers to the substitution of an amino acid in a peptide or polypeptide with another amino acid within the same class.

In some embodiments, unless otherwise specified, a conservative or semi-conservative amino acid substitution may also encompass non-naturally occurring amino acid residues that have similar chemical properties to the natural residue. These non-natural residues are typically incorporated by chemical peptide synthesis rather than by synthesis in biological systems. These include, but are not limited to, peptidomimetics and other reversed or inverted forms of amino acid moieties. Embodiments herein may, in some embodiments, be limited to natural amino acids, non-natural amino acids, and/or amino acid analogs.

Non-conservative substitutions may involve the exchange of a member of one class for a member from another class.

As used herein, the term “sequence identity” refers to the degree two polymer sequences (e.g., peptide, polypeptide, nucleic acid, etc.) have the same sequential composition of monomer subunits. The term “sequence similarity” refers to the degree with which two polymer sequences (e.g., peptide, polypeptide, nucleic acid, etc.) have similar polymer sequences. For example, similar amino acids are those that share the same biophysical characteristics and can be grouped into the families, e.g., acidic (e.g., aspartate, glutamate), basic (e.g., lysine, arginine, histidine), non-polar (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan) and uncharged polar (e.g., glycine, asparagine, glutamine, cysteine, serine, threonine, tyrosine). The “percent sequence identity” (or “percent sequence similarity”) is calculated by: (1) comparing two optimally aligned sequences over a window of comparison (e.g., the length of the longer sequence, the length of the shorter sequence, a specified window), (2) determining the number of positions containing identical (or similar) monomers (e.g., same amino acids occurs in both sequences, similar amino acid occurs in both sequences) to yield the number of matched positions, (3) dividing the number of matched positions by the total number of positions in the comparison window (e.g., the length of the longer sequence, the length of the shorter sequence, a specified window), and (4) multiplying the result by 100 to yield the percent sequence identity or percent sequence similarity. For example, if peptides A and B are both 20 amino acids in length and have identical amino acids at all but 1 position, then peptide A and peptide B have 95% sequence identity. If the amino acids at the non-identical position shared the same biophysical characteristics (e.g., both were acidic), then peptide A and peptide B would have 100% sequence similarity. As another example, if peptide C is 20 amino acids in length and peptide D is 15 amino acids in length, and 14 out of 15 amino acids in peptide D are identical to those of a portion of peptide C, then peptides C and D have 70% sequence identity, but peptide D has 93.3% sequence identity to an optimal comparison window of peptide C. For the purpose of calculating “percent sequence identity” (or “percent sequence similarity”) herein, any gaps in aligned sequences are treated as mismatches at that position.

Any peptide/polypeptides described herein as having a particular percent sequence identity or similarity (e.g., at least 70%) with a reference sequence ID number, may also be expressed as having a maximum number of substitutions (or terminal deletions) with respect to that reference sequence. For example, a sequence having at least Y% sequence identity (e.g., 90%) with SEQ ID NO:Z (e.g., 100 amino acids) may have up to X substitutions (e.g., 10) relative to SEQ ID NO:Z, and may therefore also be expressed as “having X (e.g., 10) or fewer substitutions relative to SEQ ID NO:Z.”

As used herein, the term “wild-type,” refers to a gene or gene product (e.g., protein, polypeptide, peptide, etc.) that has the characteristics (e.g., sequence) of that gene or gene product isolated from a naturally occurring source, and is most frequently observed in a population. In contrast, the term “mutant” or “variant” refers to a gene or gene product that displays modifications in sequence when compared to the wild-type gene or gene product. It is noted that “naturally-occurring variants” are genes or gene products that occur in nature, but have altered sequences when compared to the wild-type gene or gene product; they are not the most commonly occurring sequence. “Artificial variants” are genes or gene products that have altered sequences when compared to the wild-type gene or gene product and do not occur in nature. Variant genes or gene products may be naturally occurring sequences that are present in nature, but not the most common variant of the gene or gene product, or “synthetic,” produced by human or experimental intervention.

As used herein, the term “physiological conditions” encompasses any conditions compatible with living cells, e.g., predominantly aqueous conditions of a temperature, pH, salinity, chemical makeup, etc. that are compatible with living cells.

As used herein, the term “sample” is used in its broadest sense. In one sense, it is meant to include a specimen or culture obtained from any source, as well as biological and environmental samples. Biological samples may be obtained from animals (including humans) and encompass fluids, solids, tissues, and gases. Biological samples include blood products, such as plasma, serum, and the like. Sample may also refer to cell lysates or purified forms of the enzymes, peptides, and/or polypeptides described herein. Cell lysates may include cells that have been lysed with a lysing agent or lysates such as rabbit reticulocyte or wheat germ lysates. Sample may also include cell-free expression systems. Environmental samples include environmental material such as surface matter, soil, water, crystals, and industrial samples. Such examples are not however to be construed as limiting the sample types applicable to the present invention.

As used herein, the terms “fusion,” “fusion polypeptide,” and “fusion protein” refer to a chimeric protein containing a first protein or polypeptide of interest (e.g., substantially non-luminescent peptide) joined to a second different peptide, polypeptide, or protein (e.g., interaction element).

As used herein, the terms “conjugated” and “conjugation” refer to the covalent attachment of two molecular entities (e.g., post-synthesis and/or during synthetic production). The attachment of a peptide or small molecule tag to a protein or small molecule, chemically (e.g., “chemically” conjugated) or enzymatically, is an example of conjugation.

The term “binding moiety” refers to a domain that specifically binds an antigen or epitope independently of a different epitope or antigen binding domain. A binding moiety may be an antibody, antibody fragment, a receptor domain that binds a target ligand, proteins that bind to immunoglobulins (e.g., protein A, protein G, protein A/G, protein L, protein M), a binding domain of a proteins that bind to immunoglobulins (e.g., protein A, protein G, protein A/G, protein L, protein M), oligonucleotide probe, peptide nucleic acid, DARPin, aptamer, affimer, a purified protein (either the analyte itself or a protein that binds to the analyte), and analyte binding domain(s) of proteins etc. Table A provides a lists of exemplary binding moieties that could be used singly or in various combinations in methods, systems, and assays (e.g., immunoassays) herein.

As used herein, the term “antibody” refers to a whole antibody molecule or a fragment thereof (e.g., fragments such as Fab, Fab′, and F(ab′)₂, variable light chain, variable heavy chain, Fv, it may be a polyclonal or monoclonal or recombinant antibody, a chimeric antibody, a humanized antibody, a human antibody, etc. As used herein, when an antibody or other entity “specifically recognizes” or “specifically binds” an antigen or epitope, it preferentially recognizes the antigen in a complex mixture of proteins and/or macromolecules, and binds the antigen or epitope with affinity which is substantially higher than to other entities not displaying the antigen or epitope. In this regard, “affinity which is substantially higher” means affinity that is high enough to enable detection of an antigen or epitope which is distinguished from entities using a desired assay or measurement apparatus. Typically, it means binding affinity having a binding constant (Ka) of at least 10⁷ M⁻¹ (e.g., >10⁷ M⁻¹, >10⁸M⁻¹, >10⁹ M⁻¹, >10¹⁰ M⁻¹, >10¹¹M⁻¹, >10¹²M⁻¹, >10¹³ M⁻¹, etc.). In certain such embodiments, an antibody is capable of binding different antigens so long as the different antigens comprise that particular epitope. In certain instances, for example, homologous proteins from different species may comprise the same epitope.

As used herein, the term “antibody fragment” refers to a portion of a full-length antibody, including at least a portion of the antigen binding region or a variable region. Antibody fragments include, but are not limited to, Fab, Fab′, F(ab′)₂, Fv, scFv, Fd, variable light chain, variable heavy chain, diabodies, and other antibody fragments that retain at least a portion of the variable region of an intact antibody. See, e.g., Hudson et al. (2003) Nat. Med. 9:129-134; herein incorporated by reference in its entirety. In certain embodiments, antibody fragments are produced by enzymatic or chemical cleavage of intact antibodies (e.g., papain digestion and pepsin digestion of antibody) produced by recombinant DNA techniques, or chemical polypeptide synthesis. For example, a “Fab” fragment comprises one light chain and the Cm and variable region of one heavy chain. The heavy chain of a Fab molecule cannot form a disulfide bond with another heavy chain molecule. A “Fab′” fragment comprises one light chain and one heavy chain that comprises additional constant region, extending between the C_(H1) and C_(H2) domains. An interchain disulfide bond can be formed between two heavy chains of a Fab′ fragment to form a “F(ab′)₂” molecule. An “Fv” fragment comprises the variable regions from both the heavy and light chains, but lacks the constant regions. A single-chain Fv (scFv) fragment comprises heavy and light chain variable regions connected by a flexible linker to form a single polypeptide chain with an antigen-binding region. Exemplary single chain antibodies are discussed in detail in WO 88/01649 and U.S. Pat. Nos. 4,946,778 and 5,260,203; herein incorporated by reference in their entireties. In certain instances, a single variable region (e.g., a heavy chain variable region or a light chain variable region) may have the ability to recognize and bind antigen. Other antibody fragments will be understood by skilled artisans.

As used herein, the term “peptide tag” refers to a peptide that may be attached (e.g., post-synthesis or during synthetic production) or fused to another entity (e.g., protein of interest, molecule of interest, interaction element, co-localization element, etc.). The peptide tag may or may not be attached to another entity. Typically, as used herein, a peptide tag is capable of forming a bioluminescent complex with another peptide tag and a polypeptide under appropriate conditions. In embodiments in which a peptide tag is attached to another entity, a peptide tag is chemically conjugated to another molecule (e.g., peptide, polypeptide, nucleic acid, other small molecules or macromolecules), chemically synthesized to be a part of another molecule, or genetically fused to another peptide or polypeptide molecule, etc.

As used herein, the term “polypeptide component” is used synonymously with the term “polypeptide component of a bioluminescent complex.” Typically, as used herein, a polypeptide component is capable of forming a bioluminescent complex with a pair of peptide tags, under appropriate conditions.

As used herein, the term “an Oplophorus luciferase” (“an OgLuc”) refers to a luminescent polypeptide having significant sequence identity, structural conservation, and/or the functional activity of the luciferase produce by and derived from the deep-sea shrimp Oplophorus gracilirostris. In particular, an OgLuc polypeptide refers to a luminescent polypeptide having significant sequence identity, structural conservation, and/or the functional activity of the mature 19 kDa subunit of the Oplophorus luciferase protein complex (e.g., without a signal sequence) such as SEQ ID NOs: 1 (WT OgLuc) and 3 (NanoLuc®), which comprises 10 β strands (β1, β2, β3, β4, β5, β6, β7, β8, β9, β10) and utilize substrates such as coelenterazine or coelenterazine derivatives to produce luminescence.

As used herein, the term “β9-like peptide” refers to a peptide (or peptide tag) comprising significant sequence identity, structural conservation, and/or the functional activity of the β (beta) 9 strand of an OgLuc polypeptide. In particular, a β9-like peptide is a peptide capable of structurally complementing an OgLuc polypeptide lacking a β9 strand resulting in enhanced luminescence of the complex compared to the OgLuc polypeptide in the absence of the β9-like peptide.

As used herein, the term “β10-like peptide” refers to a peptide (or peptide tag) comprising significant sequence identity, structural conservation, and/or the functional activity of the β (beta) 10 strand of an OgLuc polypeptide. In particular, a β10-like peptide is a peptide capable of structurally complementing an OgLuc polypeptide lacking a β10 strand resulting in enhanced luminescence of the complex compared to the OgLuc polypeptide in the absence of the β10-like peptide. Other “βX-like peptides” may be similarly named (e.g., β1-like, β2-like, β3-like, β4-like, β5-like, β6-like, β7-like, β8-like, β9-like).

As used herein, the term “β₁₋₈-like polypeptide” refers to a polypeptide bearing sequence and structural similarity to β (beta) strands 1-8 of an OgLuc polypeptide, but lacking β (beta) strands 9 and 10.

DETAILED DESCRIPTION

Provided herein are bioluminescent polypeptides and compositions and methods for the assembly of a tripartite or multipartite bioluminescent complex. In particular embodiments, a bioluminescent complex is formed upon the interaction of three or more peptide and/or polypeptide components.

Experiments conducted during development of embodiments herein demonstrate that a tripartite luciferase comprising two small peptide elements (e.g., a β10-like peptide and β9-like peptide) and one polypeptide element (e.g., β₁₋₈-like polypeptide) assemble to form a luminescent complex. Experiments conducted during development of embodiments herein further demonstrate the formation of a bioluminescent complex from up to five fragments of a luciferase (or variants of such fragments), such as a polypeptide fragment (or variants thereof) and one or more peptide, dipeptide, or tripeptide fragments (or variants of such fragments).

The commercially-available NANOLUC luciferase (Promega Corporation) comprises 10 β (beta) strands (β1, β2, β3, β4, β5, β6, β3, β8, β9, β10). U.S. Pat. No. 9,797,889 (herein incorporated by reference in its entirety) describes development and use of a complementation system comprising a β₁₋₉-like polypeptide and a β₁₀-like peptide (the actual polypeptide and peptide sequences in U.S. Pat. No. 9,797,889 differ from the corresponding sequences in NANOLUC and wild-type native OgLuc).

In experiments conducted during development of embodiments herein, a β₁₋₉-like polypeptide was further split by removal of the β9 strand. The remaining portion (a β₁₋₈-like polypeptide) is referred to herein as LgTrip 2098 (SEQ ID NO: 17; or SEQ ID NO: 31 (with His tag)). Experiments attempted to reconstitute a luminescent complex from LgTrip and two peptides corresponding to the β9 (SmTrip9 pep245; SEQ ID NO: 23) and β10 (SmTrip10 pep86; HiBit, a β10 sequence optimized for use in a high affinity bipartite system; SEQ ID NO: 15) strands. Experiments demonstrated that LgTrip 2098 (SEQ ID NO: 17; or SEQ ID NO: 31 (with His tag)) expressed poorly in E. coli, was unstable, and was susceptible to surface inactivation. Experiments were conducted during development of embodiments herein to develop artificial variants that exhibit one or more (e.g., all) of enhanced stability, enhanced expression, enhanced activity, enhanced molecular interactions, etc., and is capable of being used in a system to reconstitute a bioluminescent complex with peptides corresponding to the β9 (e.g., β9-like peptides (e.g., SmTrip9 pep245; SEQ ID NO: 23)) and β10 (e.g., β10-like peptides (e.g., SmTrip10 pep86; HiBiT; SEQ ID NO: 25)) strands. Experiments conducted during development of embodiments herein demonstrate, for example, that LgTrip 3092 (SEQ ID NO: 19) or LgTrip 3546 (SEQ ID NO: 51) are capable of forming a luminescent complex with suitable β9-like (e.g., SmTrip9 pep245; SEQ ID NO: 23) and β10-like (e.g., SmTrip10 pep86; HiBiT; SEQ ID NO: 25) peptides. Experiments were conducted during development of embodiments herein to develop artificial polypeptide components (e.g., SEQ ID NOs: 19, 21, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107, 109, 111, 113, 115, 117, 119, 121, 123, 125, 127, 129, 131, and additional variants thereof) and peptide tags (e.g., the peptides listed in Table 1 and additional variants thereof) with enhanced characteristics for luminescent complex reconstitution.

Further experiments conducted during development of embodiments herein demonstrate that NANOLUC-based bioluminescent complexes can be formed using constructs comprising other polypeptide components (e.g., β₁₋₅-like, β₁₋₆-like, β₁₋₇-like, etc.) and corresponding combinations of complimentary peptides (e.g., β₆-like, β₇-like, β₈-like, β₉-like, β₁₀-like), dipeptides (e.g., β₆₋₇-like, β₇₋₈-like, β₈₋₉-like, β₉₋₁₀-like), tripeptides (e.g., β₆₋₈-like, β₇₋₉-like, β₈₋₁₀-like), polypeptides (e.g., β₆₋₁₀-like, β₆₋₉-like, β₇₋₁₀-like, etc.) derived from the NANOLUC-based, NanoBiT®-based, and NanoTrip™-based systems, polypeptides, and peptide described herein. The experiments conducted during development of embodiments herein demonstrate the formation of a bioluminescent complex from two or more (e.g., 2, 3, 4, 5, etc.) peptide and polypeptide components that collectively comprise the full length of a luciferase construct (e.g., a full length luciferase polypeptide comprising 40% or greater (e.g., 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, or ranges therebetween) sequence identity with SEQ ID NO: 788 or 789).

In some embodiments, provided herein are compositions and methods for the assembly of a bioluminescent complex from two peptide tags (e.g., β9-like (e.g., SmTrip9) and β10-like (e.g., SmTrip10) peptides) and a polypeptide component (e.g., β₁₋₈-like (e.g., LgTrip) polypeptide).

In some embodiments, provided herein are compositions and methods for the assembly of a bioluminescent complex from a polypeptide component (e.g., a β₁₋₅-like, β₁₋₆-like, β₁₋₇-like , or β₁₋₈-like polypeptide), and complementary peptide(s) (e.g., β₆-like, β₇-like, β₈-like, β₉-like, β₁₀-like), dipeptide(s) (e.g., β₆₋₇-like, β₇₋₈-like, β₈₋₉-like, β₉₋₁₀-like), tripeptide (e.g., β₆₋₈-like, β₇₋₉-like, β₈₋₁₀-like), and/or polypeptides (e.g., β₆₋₁₀-like, β₆₋₉-like, β₇₋₁₀-like, etc.).

In some embodiments, one or more (e.g., two, three, four, five, etc.) of the peptide tags and the polypeptide component are not fragments of a preexisting protein (e.g., are not structurally-complementary subsequences of a known polypeptide sequence). However, in other embodiments, one or more of the peptide tags and the polypeptide component may be fragments of a known or existing protein, polypeptide, or peptide. In certain embodiments, the bioluminescent activity of the polypeptide component (of the bioluminescent complex) is enhanced (e.g., 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, 10²-fold, 10³-fold, 10⁴-fold, 10⁵-fold, 10⁶-fold, or more) via structural complementation with the two peptide tags. In some embodiments, provided herein are peptide (peptide tags)/polypeptide elements that are capable of assembling into a bioluminescent complex for the purpose of, for example, detecting and monitoring molecular interactions (e.g., protein-protein, protein-DNA, protein-RNA interactions, RNA-DNA, protein-small molecule, RNA-small-molecule, DNA-DNA, RNA-RNA, PNA-DNA, PNA-RNA, etc.). In some embodiments, the peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptide thereof) are fused, or otherwise linked to interaction elements. In particular embodiments, the peptide/dipeptide/tripeptide tags and polypeptide components, when for the purpose of detecting/monitoring molecular interactions, do not form a complete bioluminescent complex without facilitation by the interaction between interaction elements. However, upon interaction (e.g., binding) of the interaction elements to each other (or to a target molecule or complex), formation of the bioluminescent complex is facilitated. In some embodiments, the bioluminescent signal from the bioluminescent complex (or the capacity to produce such a signal in the presence of substrate) serves as a reporter for the formation of a complex by the interaction elements. If an interaction complex is formed, then a bioluminescent complex is formed, and a bioluminescent signal is detected/measured/monitored (e.g., in the presence of substrate). If an interaction complex fails to form (e.g., due to unfavorable conditions, due to unstable interaction between the interaction elements, due to incompatible interaction elements), then a bioluminescent complex does not form, and a bioluminescent signal is not produced (e.g., in the presence of substrate). In some embodiments, the bioluminescent signal from the bioluminescent complex (or the capacity to produce such a signal in the presence of substrate) serves as a reporter for the binding of the interaction elements to a target. If target-binding occurs, then a bioluminescent complex is formed and a bioluminescent signal is detected/measured/monitored (e.g., in the presence of substrate). If target-binding fails to occur (e.g., due to unfavorable conditions, due to unstable interaction between an interaction element and target, due to the absence of target, etc.), then a bioluminescent complex does not form and a bioluminescent signal is not produced.

In certain embodiments, interaction elements are two molecules of interest (e.g., protein(s) of interest, small molecule(s) of interest, etc.). For example, assays can be performed to detect the interaction of two molecules of interest by tethering each one to separate peptide/dipeptide/tripeptide tag (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof). If the molecules of interest interact (e.g., transiently interact, stably interact, etc.), the peptide/dipeptide/tripeptide tags are brought into close proximity in a suitable conformation, and a bioluminescent complex is formed between the peptide/dipeptide/tripeptide tags and the polypeptide component of the bioluminescent complex (and bioluminescent signal is produced/detected (e.g., in the presence of substrate)). In the absence of an interaction between the molecules of interest, the peptide/dipeptide/tripeptide tags are not brought into close proximity and/or arranged in an orientation to facilitate complex formation with the polypeptide component of the bioluminescent complex, the bioluminescent complex is not formed, and a bioluminescent signal is not produced (in the presence of substrate). Such embodiments can be used to study the effect of inhibitors on complex formation, the effect of mutations on complex formation, the effect of conditions (e.g., temperature, pH, etc.) on complex formation, the interaction of a small molecule (e.g., potential therapeutic) with a target molecule, etc.

In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptide thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are provided that are capable of assembling into a bioluminescent complex without facilitation by interaction elements. In such embodiments, a bioluminescent complex will form when the peptide/dipeptide/tripeptide tags and polypeptide component are together within the same sample, subcellular compartment, cell, tissue, etc. (e.g., co-localized). In some embodiments, provided herein peptide/dipeptide/tripeptide (tags)/polypeptide elements that are capable of assembling into a bioluminescent complex for use in detecting and monitoring co-localization (e.g., without molecular interaction) of molecular elements (e.g., protein(s), nucleic acid(s), small molecule(s), lipid, carbohydrate, cellular structure, etc.). In some embodiments, a bioluminescent complex is formed from peptide/dipeptide/tripeptide tags and a polypeptide component that collectively span a full β1-like to β10-like sequence. In some embodiments, the peptide/dipeptide/tripeptide tags are fused or otherwise linked to co-localization elements. In particular embodiments, particularly for the purpose of detecting/monitoring co-localization (e.g., without molecular interaction), the peptide/dipeptide/tripeptide tags and polypeptide components are capable of forming a bioluminescent complex without facilitation (e.g., without interaction elements). Upon co-localization (e.g., within the same cell, on the same surface, with the same cellular compartment, within the same tissue, etc.) of the co-localization elements (e.g., fused to the peptide/dipeptide/tripeptide tags), formation of the bioluminescent complex (from the peptide/dipeptide/tripeptide tags and the polypeptide component), with or without interaction of the co-localization elements, is facilitated. In some embodiments, the bioluminescent signal from the bioluminescent complex (or the capacity to produce such a signal in the presence of substrate) serves as a reporter for co-localization of the co-localization elements. If the co-localization elements co-localize, then a bioluminescent complex of the polypeptide component and the peptide/dipeptide/tripeptide tags fused to the co-localization elements is formed, and a bioluminescent signal is detected/measured/monitored (e.g., in the presence of substrate). If the co-localization elements do not co-localize, then a bioluminescent complex does not form, and a bioluminescent signal is not produced (e.g., in the presence of substrate).

In certain embodiments, the co-localization pair comprises two molecules of interest (e.g., protein(s) of interest, small molecule(s) of interest, etc.). For example, assays can be performed to detect the co-localization (e.g., within a cell, within a cellular compartment, within a tissue, etc.) of two molecules of interest by tethering each one to a separate dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof). If the molecules of interest co-localize, the peptide tags are brought into close proximity in a suitable conformation, and a bioluminescent complex is formed with the polypeptide component polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide), and bioluminescent signal is produced/detected (e.g., in the presence of substrate). In the absence of co-localization of the molecules of interest, the polypeptide components and peptide/dipeptide/tripeptide tags tags do not interact to form a complex, and a bioluminescent signal is not produced (e.g., in the presence of substrate). Such embodiments can be used to study co-localization of molecules of interest under various conditions.

In some embodiments, systems, assays, and devices comprising dipeptide/tripeptide tags tags e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are provided for the detection of an analyte (e.g., small molecule, peptide, protein, antibody, nucleic acid, etc.) in a sample. In some embodiments, peptide/dipeptide/tripeptide tags are tethered or fused with detection/binding agents (e.g., binding moiety, binding sequence, etc.) that recognize the target analyte, target analytes, secondary analytes that are bound by the target analyte, secondary binding agents that bind to primary binding agents, etc. In some embodiments, various combinations of peptide/dipeptide/tripeptide tags tethered/fused to the aforementioned detection/binding agents are used in assays and devices for the detection/quantification/identification of analytes in a sample. Exemplary systems that find use in assays and devices are depicted in, for example, FIGS. 51-56 and described herein.

In some embodiments, provided herein are compositions and methods for the assembly of a bioluminescent complex from a dipeptide (e.g., a β9/β10-like dipeptide) and a polypeptide component (e.g., β₁₋₈-like (e.g., LgTrip) polypeptide). In some embodiments, the dipeptide and the polypeptide component are not fragments of a preexisting protein (e.g., are not structurally-complementary subsequences of a known polypeptide sequence). However, in other embodiments, the dipeptide and/or the polypeptide component may be fragments of a known or existing protein, polypeptide, or peptide. In certain embodiments, the bioluminescent activity of the polypeptide component (of the bioluminescent complex) is enhanced (e.g., 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, 10²-fold, 10³-fold, 10⁴-fold, 10⁵-fold, 10⁶-fold, or more) via structural complementation with the dipeptide. In some embodiments, a β₁₋₈-like polypeptide exhibits lower background luminescence than a β₁₋₉-like polypeptide. In some embodiments, a β₁₋₈-like polypeptide exhibits increased thermal and chemical stability compared to a β₁₋₉-like polypeptide.

The above combinations are not limiting and other combinations         of peptide, dipeptide, tripeptide, and polypeptide components         are within the scope herein.

In some embodiments, a β1-5-like polypeptide comprises positions 1-102 of SEQ ID NO: 788. In some embodiments, a β1-6-like polypeptide comprises positions 1-124 of SEQ ID NO: 788. In some embodiments, a β1-7-like polypeptide comprises positions 1-133 of SEQ ID NO: 788. In some embodiments, a β1-8-like polypeptide comprises positions 1-148 of SEQ ID NO: 788.

In some embodiments, a set of β5-10-like peptides/dipeptide/tripeptides/polypeptide collectively comprise positions 103-170 of SEQ ID NO: 788 or 789. In some embodiments, a set of β6-10-like peptides/dipeptide/tripeptides/polypeptide collectively comprise positions 125-170 of SEQ ID NO: 788 or 789. In some embodiments, a set of β7-10-like peptides/dipeptide/tripeptides/polypeptide collectively comprise positions 134-170 of SEQ ID NO: 788 or 789. In some embodiments, a set of β8-10-like peptides/dipeptide/tripeptides/polypeptide collectively comprise positions 149-170 of SEQ ID NO: 788 or 789.

In some embodiments, one or more components of a bioluminescent complex span partial beta strands of the base luciferases (e.g., OgLuc, NANOLUC, SEQ ID NO: 788, SEQ ID NO: 789, etc.) described herein. The separations between peptide, dipeptide, tripeptide, and polypeptide components may reside at the split points between the beta strands or may appear at a position −1, −2, −3, −4, −5, +1, +2, +3, +4, +5, or more from the split points identified by the sequences herein. In some embodiments, peptide, dipeptide, tripeptide, and polypeptide components that span the full sequence of a base luciferases (e.g., OgLuc, NANOLUC, SEQ ID NO: 788, SEQ ID NO: 789, etc.) described herein are capable of forming a bioluminescent complex, even if the split points for the components are not between the beta strands.

For example, a split site between β5 and β6 may occur between positions 102 and 103 of SEQ ID NO: 788, or in some embodiments such a split site may occur at a position up to 5 residues before or after that position (e.g., after position 96, 97, 98, 99, 100, 101, 103, 104, 105, 106, 107). In some embodiments, a split site between β6 and β7 may occur between positions 124 and 125 of SEQ ID NO: 788, or in some embodiments such a split site may occur at a position up to 5 residues before or after that position (e.g., after position 118, 119, 120, 121, 122, 123, 125, 126, 127, 128, 129). In some embodiments, a split site between β7 and β8 may occur between positions 133 and 134 of SEQ ID NO: 788, or in some embodiments such a split site may occur at a position up to 5 residues before or after that position (e.g., after position 127, 128, 129, 130, 131, 132, 134, 135, 136, 137, 138). In some embodiments, a split site between β8 and β9 may occur between positions 148 and 149 of SEQ ID NO: 788, or in some embodiments such a split site may occur at a position up to 5 residues before or after that position (e.g., after position 142, 143, 144, 145, 146, 147, 149, 150, 151, 152, 153).

In some embodiments, two peptide, dipeptide, tripeptide, and polypeptide components that are sequentially adjacent within the base luciferase (e.g., OgLuc, NANOLUC, SEQ ID NO: 788, SEQ ID NO: 789, etc.) sequence comprise all of the amino acids of that corresponding portion of the base sequence. In some embodiments, one or more (e.g., 1, 2, 3, 4, 5, or more) amino acids adjacent to the split point in the base sequence are absent from the corresponding peptide, dipeptide, tripeptide, and/or polypeptide components.

In some embodiments, provided herein are peptides comprising 40% or greater (e.g., 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%) sequence identity with one of the following:

In some embodiments, a polypeptide component (e.g., of a set of peptides/polypeptides, or a bioluminescent complex, etc.) comprises 40% or greater (e.g., 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%) sequence identity with one of SEQ ID NOS: 788, 789, 790, 791, 792, and 793.

In some embodiments, peptide/dipeptide/tripeptide components (e.g., tags) (e.g., of a set of peptides/polypeptides, or a bioluminescent complex, etc.) collectively comprise 40% or greater (e.g., 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%) sequence identity with one of SEQ ID NOS: 794, 795, 796, 797, 798, 799, 800, and 801.

In some embodiments, provided herein are sets of components and complexes of the peptides, dipeptides, tripeptides, and polypeptides listed above. In particular embodiments, sets of components are selected that span all ten of the beta strands of a base luciferase sequence.

In some embodiments, the interaction, co-localization, detection, and other methods, assays, and technologies described for use with the two-peptide tag systems herein (e.g., β9-like (e.g., SmTrip9) peptide, β10-like (e.g., SmTrip10) peptides and polypeptide component ((e.g., β1-8-like (e.g., LgTrip) polypeptide)), also find use with the dipeptide systems described herein (e.g., β9/10-like dipeptide and polypeptide component). In some embodiments, a dipeptide has high affinity for a polypeptide component; in such embodiments, a bioluminescent complex forms when the dipeptide and polypeptide component are brought into contact (e.g., co-localize, are added to the sample sample, etc.) without facilitation. In some embodiments, a dipeptide has low affinity for a polypeptide component; in such embodiments, a bioluminescent complex will not form when the dipeptide and polypeptide component are brought into contact (e.g., co-localize, are added to the sample sample, etc.) without facilitation. Like the two-peptide tag systems herein (e.g., β9-like (e.g., SmTrip9) peptide, β10-like (e.g., SmTrip10) peptides and polypeptide component (e.g., β1-8-like (e.g., LgTrip) polypeptide)), dipeptide/polypeptide pairs of varying affinities may be selected for different applications. In some embodiments, systems, methods, and assays for two-component complementation systems are described in U.S. Pat. No. 9,797,890 (herein incorporated by reference in its entirety), and all such systems, methods, and assays find use with the dipeptide/polypeptide systems described herein.

In some embodiments, the interaction, co-localization, detection, and other methods, assays, and technologies described for use with the two-peptide tag systems herein (e.g., β9-like (e.g., SmTrip9) peptide, β10-like (e.g., SmTrip10) peptides and polypeptide component ((e.g., β1-8-like (e.g., LgTrip) polypeptide)), also find use with systems comprising any suitable combination fo peptides, dipeptides, trippeptides, and polypeptides, as described herein. In some embodiments, the components have high affinity for one another; in such embodiments, a bioluminescent complex forms when the components are brought into contact (e.g., co-localize, are added to the sample sample, etc.) without facilitation. In some embodiments, one or more of the components have low affinity for one or more of the other components; in such embododiments, a bioluminescent complex will not form when the components are brought into contact (e.g., co-localize, are added to the sample sample, etc.) without facilitation. Like the two-peptide tag systems herein (e.g., β9-like (e.g., SmTrip9) peptide, β10-like (e.g., SmTrip10) peptides and polypeptide component (e.g., β1-8-like (e.g., LgTrip) polypeptide)), the other systems described herein may be provided with varying affinities for different applications. In some embodiments, systems, methods, and assays for two-component complementation systems are described in U.S. Pat. No. 9,797,890 (herein incorporated by reference in its entirety), and all such systems, methods, and assays find use with the various peptide, dipeptide, tripeptide, and polypeptide systems described herein.

In some embodiments, provided herein are complementary panels of interchangeable peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) that have variable affinities and luminescence upon formation of bioluminescent complexes therefrom (e.g., a high-affinity/high-luminescence, a moderate-affinity/high-luminescence, a low-affinity/moderate-luminescence, etc.). Utilizing different combinations of peptide/dipeptide/tripeptide tags and polypeptide components provides an adaptable system comprising various sets ranging from lower to higher affinities, luminescence, expression level, stability, solubility, and other variable characteristics. This adaptability allows the detection/monitoring/identification/quantification of analytes, molecular interactions, co-localization, and/or other characteristics to be fine-tuned to the specific molecule(s) of interest and/or conditions to be studied and expands the range of molecular interactions and/or co-localizations that can be detected/monitored/identified/quantified to include interactions with very high or low affinities. Further provided herein are methods by which non-luminescent elements and panels of non-luminescent elements are developed and tested.

In some embodiments, due to the small size of the tags (e.g., peptide tags) herein (e.g., compared to larger polypeptides and proteins), they are resistant to denaturation (they have no tertiary structure required for function).

In some embodiments, peptide/dipeptide/tripeptide tags and a polypeptide components may be selected based on the molecules or proteins of interest to be studied. In some embodiments, different peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) may require different strength, duration, and/or stability of an interaction complex (e.g., complex of interaction elements) to result in bioluminescent complex formation. In some embodiments, a highly stable interaction complex is required to produce a detectable bioluminescent signal (e.g., in the presence of a substrate). In other embodiments, even a weak or transient interaction complex results in bioluminescent complex formation. In still other embodiments, a bioluminescent complex will form in the absence of an interaction complex as long as the peptide/dipeptide/tripeptide tags and polypeptide component are co-localized. In some embodiments, the strength or extent of an interaction complex is directly proportional to the strength of the resulting bioluminescent signal. Some peptide/dipeptide/tripeptide tags/polypeptide component sets produce a detectable signal when combined with an interaction complex with a high millimolar dissociation constant (e.g., K_(d)>100 mM). Other peptide/dipeptide/tripeptide tags/polypeptide component sets require an interaction pair with a low millimolar (e.g., K_(d)<100 mM), micromolar (e.g., K_(d)<1 mM), nanomolar (e.g., K_(d)<1 μM), or even picomolar (e.g., K₁ μM) dissociation constant in order to produce a bioluminescent complex with a detectable signal.

In some embodiments, the peptide/dipeptide/tripeptide tags and/or polypeptide components herein are not fragments of a pre-existing protein (e.g., a pre-existing bioluminescent protein). In some embodiments, none of the peptide/dipeptide/tripeptide tags and polypeptide component used to form a complex are fragments of a pre-existing protein (e.g., the same pre-existing protein, a pre-existing bioluminescent protein, etc.). In some embodiments, neither the peptide tags (e.g., β9-like (e.g., SmTrip9) and β10-like (e.g., SmTrip10) peptides; β9/β10-like dipeptides; etc.) nor polypeptide component (e.g., β₁₋₈-like (e.g., LgTrip) polypeptide)) that assemble together to form a bioluminescent complex are fragments of a pre-existing protein (e.g., the same pre-existing protein, a pre-existing sdzbioluminescent protein, etc.). In some embodiments, the peptide/dipeptide/tripeptide tags or polypeptide component of a bioluminescent complex for use in embodiments of the present invention is not a subsequence of a preexisting protein. In some embodiments, non-luminescent elements for use in embodiments described herein do not comprise structurally-complementary subsequences of a preexisting protein.

In some embodiments, the peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) herein are non-luminescent or substantially non-luminescent in isolation (e.g., in the presence or absence of substrate). In some embodiments, the peptide/dipeptide/tripeptide tags herein are non-luminescent or substantially non-luminescent when associated together, in the absence of the polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) (e.g., in the presence or absence of substrate). In some embodiments, a polypeptide component is non-luminescent or substantially non-luminescent in isolation (e.g., in the presence or absence of substrate). In some embodiments, a single peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and the polypeptide component are non-luminescent or substantially non-luminescent in the absence of the second or third or fourth peptide/dipeptide/tripeptide tag (e.g., in the presence or absence of substrate). In certain embodiments, when placed in suitable conditions (e.g., physiological conditions), multiple peptide/dipeptide/tripeptide tags and a polypeptide component interact to form a bioluminescent complex and produce a bioluminescent signal in the presence of substrate.

In certain embodiments, an interaction element and/or co-localization element and a peptide/dipeptide/tripeptide tag are attached, fused, linked, connected, etc. In typical embodiments, a first peptide/dipeptide/tripeptide tag and a first interaction element (or first co-localization element) are attached to each other, and a second peptide/dipeptide/tripeptide tag and a second interaction element (or second co-localization element) are attached to each other. Attachment of peptide/dipeptide/tripeptide tags to interaction elements (or co-localization elements) may be achieved by any suitable mechanism, chemistry, linker, etc. The interaction elements (or co-localization elements) and peptide/dipeptide/tripeptide tags are typically attached through covalent connection, but non-covalent linking of the two elements is also provided. In some embodiments, the peptide/dipeptide/tripeptide tags and interaction elements (or co-localization elements) are directly connected and, in other embodiments, they are connected by a linker. In some embodiments, the peptide/dipeptide/tripeptide tags and interaction elements (or co-localization elements) are provided as genetic/recombinant fusions. In some embodiments, endogenous tagging with the peptide/dipeptide/tripeptide tags herein (e.g., under endogenous regulatory control), allows for monitoring of normal cellular functions with the tools described herein. For example, a protein of interest may be endogenously tagged (e.g., using CRISPR/Cas9) with a high affinity β9/β10-like dipeptide, and then spontaneous complementation with LgTrip (or a variant thereof) is monitored in a cell, animal, lysate, etc. In other embodiments, the peptide tags and interaction elements (or co-localization elements) are connected by chemical modification/conjugation, such as by Native chemical ligation, Staudinger ligation, “traceless” Staudinger ligation, amide coupling, methods that employ activated esters, methods to target lysine, tyrosine and cysteine residues, imine bond formation (with and without ortho-boronic acid), boronic acid/diol interactions, disulfide bond formation, copper/copper free azide, diazo, and tetrazine “click” chemistry, UV promoted thiolene conjugation, diazirine photolabeling, Diels-Alder cycloaddition, metathesis reaction, Suzuki cross-coupling, thiazolidine (Step-4) coupling, streptavidin/biotin complementation, HaloTag®/chloroalkane substrate complementation, etc. In some embodiments, peptide/dipeptide/tripeptide tags and interaction elements (or co-localization elements) are produced synthetically (e.g., solid-state synthesis, solution-phase synthesis, etc.). In some embodiments, interaction elements (or co-localization elements) are produced (e.g., synthetically or recombinantly) or obtained (e.g., from crude lysate, extracted proteins, purified proteins, etc.) by any suitable means.

In some embodiments, in which the interaction element (or co-localization element) is a peptide or polypeptide, a peptide/dipeptide/tripeptide tag (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and an interaction element (or co-localization element) are contained within a single amino acid chain. In some embodiments, a single amino acid chain comprises, consists of, or consists essentially of a peptide/dipeptide/tripeptide tag and an interaction element (or co-localization element). In some embodiments, a single amino acid chain comprises, consists of, or consists essentially of a peptide/dipeptide/tripeptide tag, an interaction element (or co-localization element), optionally one or more an N-terminal sequence, a C-terminal sequence, regulatory elements (e.g., promoter, translational start site, etc.), and a linker sequence. In some embodiments, the peptide/dipeptide/tripeptide tag and interaction element (or co-localization element) are contained within a fusion polypeptide. In some embodiments, the first fusion of peptide/dipeptide/tripeptide tag and interaction element (or co-localization element) and the second fusion of peptide/dipeptide/tripeptide tag and interaction element (or co-localization element) are expressed separately; however, in other embodiments, a fusion protein is expressed that comprises or consist of both of the interaction (or co-localization) and peptide/dipeptide/tripeptide tags.

In some embodiments, a first fusion protein comprising a first peptide/dipeptide/tripeptide tag (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and first interaction element as well as a second fusion protein comprising a second peptide/dipeptide/tripeptide tag (e.g., 62 6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and second interaction element are expressed within the same cells. In some embodiments, a first fusion protein comprising a first peptide/dipeptide/tripeptide tag and first co-localization element as well as a second fusion protein comprising a second peptide/dipeptide/tripeptide tag and second co-localization element are expressed within the same cells. In some embodiments, the first and second fusion proteins are purified and/or isolated from the cells. In some embodiments, the interaction and/or co-localization of the fusion proteins is assayed within the cells. In some embodiments, the interaction and/or co-localization of the fusion proteins is assayed within a lysate of the cells. In other embodiments, first and second fusion proteins are expressed in separate cells and combined (e.g., following purification and/or isolation, following fusion of the cells or portions of the cells, by transfer of a fusion protein from one cell to another, or by secretion of one or more fusion proteins into the extracellular medium) for signal detection. In some embodiments, one or more fusion proteins are expressed in cell lysate (e.g., rabbit reticulocyte lysate) or in a cell-free system. In some embodiments, one or more fusion proteins are expressed from the genome of a virus or other cellular pathogen. In some embodiments, the polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) and any other peptide/dipeptide/tripeptide components (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) for complex formation (with the first and second fusion proteins) is expressed in the same cell or cell lysate as one or both of the tag- containing fusion proteins. In some embodiments, the peptide/dipeptide/tripeptide/polypeptide components for complex formation with the peptide/dipeptide/tripeptide tags (within the first and second fusion proteins) are expressed in a different cell or cell lysate as one or both of the peptide-tag-containing fusion proteins. In some embodiments, the peptide/dipeptide/tripeptide/polypeptide components for complex formation with the peptide/dipeptide/tripeptide tags (within the first and second fusion proteins) is added to a cell, cell lysate, or other sample comprising the peptide-tag-containing fusion proteins.

In some embodiments, the systems (e.g., peptide/dipeptide/tripeptide tags, peptide/dipeptide/tripeptide/polypeptide components, substrates, vectors, etc.) and methods herein find use in the analysis of a sample (e.g., detection/quantification/identification/monitoring of co-localization, a molecular interaction, a target, etc.). In some embodiments, one or more of the components of a system herein are added to and/or provided or expressed within a sample. Suitable samples that may find use in embodiments herein include, but are not limited to: blood, plasma, sera, urine, saliva, cells, cell lysates, tissues, tissue homogenates, purified nucleic acids, stool, vaginal secretions, cerebrospinal fluid, allantoic fluid, water, biofilm, soil, dust, food, beverage, agriculture products, plants, etc.

In certain embodiments, nucleic acids, DNA, RNA, vectors, etc. are provided that encode the peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide), fusion polypeptides, fusion proteins, etc. described herein. Such nucleic acids and vectors may be used for expression, transformation, transfection, injection, etc.

In some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and interaction, co-localization element, or binding agent are connected by a linker. In some embodiments, a linker connects the signal and interaction or co-localization elements while providing a desired amount of space/distance between the elements. In some embodiments, a linker allows both the signal and interaction elements to form their respective complexes (e.g., luminescent complex and interaction complex) simultaneously. In some embodiments, a linker assists the interaction element in facilitating the formation of a luminescent complex. In some embodiments, when an interaction complex is formed, the linkers that connect each peptide/dipeptide/tripeptide tag to their respective interaction elements position the peptide tags at the proper distance and conformation to form a bioluminescent complex. In some embodiments, an interaction or co-localization element and peptide/dipeptide/tripeptide tag are held in close proximity (e.g., <4 monomer units) by a linker. In some embodiments, a linker provides a desired amount of distance (e.g., 1, 2, 3, 4, 5, 6 . . . 10 . . . 20, or more monomer units) between peptide tags and interaction elements (e.g., to prevent undesirable interactions between peptide/dipeptide/tripeptide tags and interaction or co-localization elements, for steric considerations, to allow proper orientation of non-luminescent element upon formation of interaction complex, to allow propagation of a complex-formation from interaction complex to luminescent complex, etc.). In certain embodiments, a linker provides appropriate attachment chemistry between the peptide/dipeptide/tripeptide tags and interaction elements. A linker may also improve the synthetic process of making the peptide/dipeptide/tripeptide tag and interaction or co-localization element (e.g., allowing them to be synthesized as a single unit, allowing post synthesis connection of the two elements, etc.).

In some embodiments, a linker is any suitable chemical moiety capable of linking, connecting, or tethering a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) or polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) to an interaction element or co-localization element. In some embodiments, a linker is a polymer of one or more repeating or non-repeating monomer units (e.g., nucleic acid, amino acid, carbon-containing polymer, carbon chain, etc.). When a peptide/dipeptide/tripeptide tag and an interaction, co-localization element, or binding agent are part of a fusion protein, a linker (when present) is typically an amino acid chain. When a peptide/dipeptide/tripeptide tag and interaction element, co-localization element, or binding agent are tethered together after the expression of the individual elements, a linker may comprise any chemical moiety with functional (or reactive) groups at either end that are reactive with functional groups on the peptide tag and interaction or co-localization elements, respectively. Any suitable moiety capable of tethering the signal and interaction elements, co-localization element, and/or binding agent may find use as a linker.

A wide variety of linkers may be used. In some embodiments, the linker is a single covalent bond. In some embodiments, the linker comprises a linear or branched, cyclic or heterocyclic, saturated or unsaturated, structure having 1-20 nonhydrogen atoms (e.g., C, N, P, O and S) and is composed of any combination of alkyl, ether, thioether, imine, carboxylic, amine, ester, carboxamide, sulfonamide, hydrazide bonds and aromatic or heteroaromatic bonds. In some embodiments, linkers are longer than 20 non-hydrogen atoms (e.g. 21 non-hydrogen atoms, 25 non-hydrogen atoms, 30 non-hydrogen atoms, 40 non-hydrogen atoms, 50 non-hydrogen atoms, 100 non-hydrogen atoms, etc.) In some embodiments, the linker comprises 1-50 non-hydrogen atoms (in addition to hydrogen atoms) selected from the group of C, N, P, O, and S (e.g. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40,41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 non-hydrogen atoms).

The scope of embodiments herein is not limited by the types of linkers available. The peptide/dipeptide/tripeptide tags, polypeptide components, and interaction elements, co-localization elements, or binding agents are linked either directly (e.g. linker consists of a single covalent bond) or linked via a suitable linker. Embodiments are not limited to any particular linker group. A variety of linker groups are contemplated, and suitable linkers could comprise, but are not limited to, alkyl groups, methylene carbon chains, ether, polyether, alkyl amide linker, a peptide linker, a modified peptide linker, a Poly(ethylene glycol) (PEG) linker, a streptavidin-biotin or avidin-biotin linker, polyaminoacids (e.g. polylysine), functionalized PEG, polysaccharides, glycosaminoglycans, dendritic polymers (W093/06868 and by Tomalia et al. in Angew. Chem. Int. Ed. Engl. 29:138-175 (1990), herein incorporated by reference in their entireties), PEG-chelant polymers (W94/08629, W094/09056 and W096/26754, herein incorporated by reference in their entireties), oligonucleotide linker, phospholipid derivatives, alkenyl chains, alkynyl chains, disulfide, or a combination thereof. In some embodiments, the linker is cleavable (e.g., enzymatically (e.g., TEV protease site), chemically, photoinduced, etc.

In some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide), recognition element, interaction element, co-localization element, binding agent, analyte, substrate, etc. is attached (e.g., via any suitable chemistry) to, or contained within, a solid surface or matrix. In some embodiments, one or more system components are attached (e.g., via any suitable chemistry) to, or contained within, a solid surface or matrix and other components are added (e.g., in solution (e.g., in a sample)) to the solid surface or matrix.

In some embodiments, peptide tags (e.g., β9-like (e.g., SmTrip9) and β10-like (e.g., SmTrip10) peptides; β9/β10-like dipeptides; etc.) that find use in embodiments of the present invention include peptides with one or more amino acid substitutions, deletions, or additions from SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO:9, SEQ ID NO: 10, SEQ ID NO: 23, SEQ ID NO: 25, SEQ ID NO: 29. In some embodiments, a peptide tag comprises at least 40% (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99%) sequence identity or similarity with SEQ ID NO: 13.

In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) that find use in embodiments of the present invention include the peptides, dipeptides, tripeptides, and polypeptides disclosed herein and in the tables provided herein. In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) that find use in embodiments of the present invention comprise one or more amino acid substitutions, deletions, or additions relative to the peptides, dipeptides, tripeptides, and polypeptides disclosed herein and in the tables provided herein. In some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) that find use in embodiments of the present invention comprise at least 40% (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99%) sequence identity or similarity with the peptides, dipeptides, tripeptides, and polypeptides disclosed herein and in the tables provided herein.

In some embodiments, dipeptides and tripeptides that find use in embodiments herein comprise any suitable combinations of the peptides described herein and/or listed in the tables herein.

In some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) or a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) is linked (e.g., chemically) or fused to one or more additional elements (e.g., recognition element, interaction element, co-localization element, detectable element (e.g., a fluorophore (e.g., to facilitate BRET)), protein of interest, HALOTAG, etc.). In some embodiments, a peptide/dipeptide/tripeptide tag or polypeptide component is linked or fused to a cyOFP (e.g., in an Antares construct such as those described in U.S. Pat. No. 9,908,918; herein incorporated by reference in its entirety) or other fluorescent protein (e.g., to facilitate BRET). In some embodiments, a peptide/dipeptide/tripeptide tag or polypeptide component comprises one or more chemical modifications and/or unnatural amino acids or amino acid analogs to facilitate chemical conjugation of the polypeptide component with additional elements. In some embodiments, provided herein is a single peptide/dipeptide/tripeptide tag or polypeptide component fused to an acceptor fluorescent protein. In some embodiments, two or more peptide/dipeptide/tripeptide and/or polypeptide components are fused to an acceptor fluorescent protein (e.g., sandwhich fusion). In some embodiments, a peptide/dipeptide/tripeptide tag or polypeptide component is fused to two or more acceptor fluorescent protein (e.g., sandwhich fusion). In some embodiments, a LgTrip polypeptide (e.g., a β₁₋₈-like polypeptide described herein) is fused to a single fluorescent protein (e.g., cyOFP) or placed between two fluorescent proteins (e.g., two copies of a cyOFP) in a sandwich fusion.

In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) that find use in the present invention incorporate reactive groups suitable for chemical conjugation to an additional element (e.g., recognition element, interaction element, etc.). These reactive groups may be present on the N-terminus, C-terminus, or within the sequence. These reactive groups may optionally be attached to the peptide with a linker. In some cases, these peptide/dipeptide/tripeptide bearing reactive groups may be synthesized using standard synthesis and incorporated on an unnatural amino acid bearing the desired group. In some cases, the reactive group may be present on a natural amino acid (e.g. the sulfhydryl of cysteine). The additional element intended to react with a peptide tag bearing a reactive group may be a protein, an antibody, a nucleic acid, a small molecule such as a drug or a fluorophore or a surface. The peptide/dipeptide/tripeptide tag may incorporate a reactive group that is designed to react specifically with a reactive partner that has been chemically or biologically introduced on the additional element using bioorthogonal, or click, chemistry. An exemplary click reaction is copper catalyzed click where the peptide tag bears an alkyne or an azide, and the additional element bears the complementary group. Mixing these two species together in the presence of an appropriate copper catalyst causes the peptide to be covalently conjugated to the additional element through a triazole. Many other bioorthogonal reactions have been reported (for example Patterson, D. M., et al. (2014). “Finding the Right (Bioorthogonal) Chemistry.” ACS Chemical Biology 9(3): 592-605.), and peptide tags and additional elements incorporating complementary reactive species are embodiments of the present invention.

Another embodiment of the present invention are peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and/or a polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) bearing reactive groups that react with naturally occurring amino acids. Exemplary reactive groups include maleimides for reaction with cysteine and succinimidyl esters for reaction with lysine. A more comprehensive list of reactive groups can be found in Koniev, O. and A. Wagner (2015). “Developments and recent advancements in the field of endogenous amino acid selective bond forming reactions for bioconjugation.” Chem Soc Rev 44: 5495-5551. These reactive groups may be chemically or biologically introduced on a peptide/dipeptide/tripeptide/polypeptide through peptide synthesis or through other chemical modification of a peptide tag. In some embodiments, the peptide tag exists in a protected form (Isidro-Llobet, A., et al. (2009). “Amino Acid-Protecting Groups.” Chemical Reviews 109(6): 2455-2504; herein incorporated by reference in its entirety), preventing the peptide/dipeptide/tripeptide/polypeptide itself from reacting with the reactive group. These reactive groups may react with a protein in a selective fashion or in a random fashion, yielding either one conjugate or a mixture of conjugates. In some embodiments, either a defined single conjugate or a mixture can be used successfully in this invention.

Examples of peptides (e.g., β9-like (e.g., SmTrip9) and β10-like (e.g., SmTrip10) peptides; β9/β10-like dipeptides; etc.) described herein bearing reactive groups suitable for chemical conjugation to an additional element (e.g., recognition element, interaction element, etc.) are displayed in FIGS. 95-98. Other combinations of reactive groups and peptides/dipeptides/tripeptides/polypeptides are within the scope herein.

In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) described herein is fused or conjugated to a detectable element such as a fluorophore or fluorescent protein. In such embodiments, complementation to form the bioluminescent complex, and the resultant bioluminescence, results in BRET and excitement of/emission from the attached detectable element (e.g., fluorophore or fluorescent protein). In such embodiments, the bioluminescent complex is a BRET energy donor, and the detectable element (e.g., fluorophore or fluorescent protein) attached to a component of the complex (e.g., peptide tag or polypeptide component) is the BRET energy acceptor.

Suitable fluorophores for use in a BRET system with the tripartite/multipartite complementation systems described herein include, but are not limited to: xanthene derivatives (e.g., fluorescein, rhodamine, Oregon green, eosin, Texas red, etc.), cyanine derivatives (e.g., cyanine, indocarbocyanine, oxacarbocyanine, thiacarbocyanine, merocyanine, etc.), naphthalene derivatives (e.g., dansyl and prodan derivatives), oxadiazole derivatives (e.g., pyridyloxazole, nitrobenzoxadiazole, benzoxadiazole, etc.), pyrene derivatives (e.g., cascade blue), oxazine derivatives (e.g., Nile red, Nile blue, cresyl violet, oxazine 170, etc.), acridine derivatives (e.g., proflavin, acridine orange, acridine yellow, etc.), arylmethine derivatives (e.g., auramine, crystal violet, malachite green, etc.), tetrapyrrole derivatives (e.g., porphin, phtalocyanine, bilirubin, etc.), CF dye (Biotium), BODIPY (Invitrogen), ALEXA FLOUR (Invitrogen), DYLIGHT FLUOR (Thermo Scientific, Pierce), ATTO and TRACY (Sigma Aldrich), FluoProbes (Interchim), DY and MEGASTOKES (Dyomics), SULFO CY dyes (CYANDYE, LLC), SETAU AND SQUARE DYES (SETA BioMedicals), QUASAR and CAL FLUOR dyes (Biosearch Technologies), SURELIGHT DYES (APC, RPE, PerCP, Phycobilisomes)(Columbia Biosciences), APC, APCXL, RPE, BPE (Phyco-Biotech), autofluorescent proteins (e.g., YFP, RFP, mCherry, mKate), quantum dot nanocrystals, etc. In some embodiments, a fluorophore is a rhodamine analog (e.g., carboxy rhodamine analog), such as those described in U.S. patent application Ser. No. 13/682,589, herein incorporated by reference in its entirety.

In other embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) described herein is fused or conjugated to a detectable element such as a fluorophore or fluorescent protein (e.g., green fluorescent protein (GFP), enhanced GFP (EGFP), cyan fluorescent protein (CFP), yellow fluorescent protein (YFP), and variants thereof. In other embodiments, a peptide tag or polypeptide component described herein is fused or conjugated to a cyan-excitable orange-red fluorescent protein (CyOFP), such as those described in U.S. Pat. No. 9,908,918; herein incorporated by reference in its entirety. In some embodiments, the CyOFP and BRET systems described in U.S. Pat. No. 9,908,918 find use with the peptide tags and/or polypeptide components described herein (e.g., CyOFP-(β₉-like peptide), CyOFP-(β₁₀-like peptide), CyOFP-(β₁₋₈-like polypeptide), CyOFP-(β₉₋₁₀-like peptide), CyOFP-(β₉-like peptide)-CyOFP, CyOFP-(β₁₀-like peptide)-CyOFP, CyOFP-(β₁₋₈-like polypeptide)-CyOFP, CyOFP-(β₉₋₁₀-like peptide)—CyOFP, etc.). In some embodiments, such systems comprising CyOFP linked to peptide/dipeptide/tripeptide tags and/or polypeptide components herein may be referred to herein as “Antares constructs” or “Antares systems.” Such BRET systems are particularly useful in certain imaging applications (Schaub, F. X., et al. (2015) “Fluorophore-NanoLuc® BRET Reporters Enable Sensitive In Vivo Optical Imaging and Flow Cytometry for Monitoring Tumorigenesis.” Cancer Research 75(23): 5023-5033; herein incorporated by reference in its entirety).

In other embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) described herein are linked to fluorophores (e.g., directly or via a linker) for use in a constitutive BRET system (e.g., an Antares-like system). In constitutive BRET systems, the emission spectrum is shifted from the bioluminescence spectrum toward that of the fluorophore (e.g., for better sensitivity, lower scattering, desired emission wavelength, etc.). In other embodiments, peptide/dipeptide/tripeptide tags and/or polypeptide components described herein find use as functional sensors (e.g., for monitoring cellular/intracellular/intercellular processes (e.g., for detecting calcium flux or voltage (Suzuki, K., et al. (2016). “Five colour variants of bright luminescent protein for real-time multicolour bioimaging.” Nature Communications 7: 13718.; Inagaki, S., et al. (2017). “Genetically encoded bioluminescent voltage indicator for multi-purpose use in wide range of bioimaging.” Sci Rep 7: 42398; herein incorporated by reference in their entireties)), for imaging, for optogenetics, etc.).

In some embodiments, two or more of the peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are attached to a single interaction element that can access multiple conformations. In one conformation, the peptide/dipeptide/tripeptide tags and the polypeptide are unable to form a luminescent complex. Upon changing conformation, i.e., in response to a stimulus, the peptide/dipeptide/tripeptide tags are brought into a conformation where they can form a bioluminescent complex. As an example, a SmTrip9 peptide and a SmTrip10 peptide can be conjugated to calmodulin such that they do not form a luminescent complex even in the presence of LgTrip and furimazine. Upon exposure to calcium, the conformational change of calmodulin bring the SmTrip9 peptide and SmTrip10 peptide into a position whereupon addition of LgTrip makes a complex that is bioluminescent in the presence of furimazine. Many other biosensors for calcium and other stimuli (pH, voltage, etc.) are known in the literature.

In some embodiments, systems herein find use in multiplexable analyte detection. In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) that find use in the present invention are conjugated to both an interaction element and a reporter element. In some embodiments, the interaction element is an antibody or the like, and the reporter element is a small molecule fluorophore. In some embodiments, antibodies to different pathogens (e.g. Zika virus, Dengue virus, etc.) are conjugated to a peptide/dipeptide/tripeptide tag (e.g., a SmTrip9 peptide) and a fluorophore with a different and distinguishable wavelength. In this embodiment, the luminescent complex that is formed upon the antibody binding to its antigen emits light at the emission wavelength of the bound fluorophore due to bioluminescence resonance energy transfer. This allows the antibodies to all be present in the same well, device, etc., and the identity of the antigen detected to be determined by the color of the light emitted by the luminescent complex formed.

In some embodiments, polypeptide components (e.g., β1-8-like (e.g., LgTrip) polypeptide) that find use in embodiments of the present invention include polypeptides with one or more amino acid substitutions, deletions, or additions from SEQ ID NO: 5 and/or SEQ ID NO: 8.

In some embodiments, a polypeptide component comprises at least 40% (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99%) sequence identity or similarity with SEQ ID NO: 17, SEQ ID NO: 21, and/or SEQ ID NO: 302.

In some embodiments, a polypeptide component comprises at least 40% (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99%) sequence identity or similarity with SEQ ID NO: 788. In some embodiments, polypeptide component comprises 100 or fewer (e.g., 100, 90, 80, 70, 60, 50, 40, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, or ranges there between) substitutions (e.g., conservative substitutions, semi-conservative substitutions, non-conservative substations, etc.) relative to SEQ ID NO: 788. In some embodiments, a polypeptide component comprises at least 40% (e.g., >40%, >45%, >50%, >55%, >60%, >65%, >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99%) sequence identity or similarity with SEQ ID NO: 789.

Suitable recognition elements or binding moieties that find use (e.g., fused/tethered to a peptide tag, binding to an analyte, etc.) in embodiments herein, include, but are not limited to: antibodies (e.g., monoclonal, polyclonal, recombinant, animal derived, autoantibody, biotherapeutic, etc.), antibody variable heavy chain, antibody variable light chain, antibody binding fragment (Fab) [F(ab)′2], camelid, single chain variable fragment (scFv), monomeric proteins, receptor domains, affibodies, monobodies, natural and derivatized nucleic acid aptamers (e.g., RNA aptamer, DNA aptamer, chemical modified aptamer, etc.), peptide nucleic acids (PNA), locked nucleic acids (LNA), hexitol nucleic acids (HNA), protein A, G, L, M and/or domains thereof, sequence specific oligonucleotide probes (e.g., DNA probe, RNA probe, etc.), small molecule drug, antibody-oligonucleotide conjugates, darpins, nanobodies, affimers, adhirons, anticalins, phage, magnetic particles (e.g., labeled directly or labeled with a tagged recognition element), nanoparticles (e.g., polystyrene nanospheres, etc.) labeled directed or labeled with a tagged recognition element, streptavidin, antigens, etc. In some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) is linked to an oligonucleotide recognition element or binding moiety. Such constructs may find use in nucleic acid (e.g., DNA, RNA, etc.) complementation and/or detection. Exemplary peptide/oligomer probes are depicted in FIG. 99. In such exempalry constructs, a peptide/dipeptide/tripeptide comprising a reactive group (e.g., azido group (e.g., N-terminal, C-terminal, internal, etc.) or other reactive group herein) is conjugated to an oligonucleotide comprising a complementary reactive group (e.g., alkyne group (e.g., 5′-terminal, 3′-terminal, interanl, etc.) or other reactive group herein). In an exemplary embodiment, peptide oligonuceleotide probes are prepard by combing components and reagents (e.g., oligonucleotide (1 mg,161 nmol, in water); triethylammonium acetate buffer (40 uL, 1M in water); aminoguanidine hydrochloride (8 uL, 50 mM in water); peptide (2.8 mg, 1.93 umol, in DMSO); copper(II) TBTA solution (10 mM in 1:1 water/DMSO); ascorbic acid solution (50 mM in water); final volume is 300 uL, 1:1 Water:DMSO); vortexing and heat for 30 min at 60° C.; filtering using Illustra NAP-5 column; exchanging buffer into TE buffer that is RNase and DNase free; and storing at −20° C. In embodiments, in which a molecular interaction is being monitored/detected, peptide/dipeptide/tripeptide tags and a polypeptide component are selected that have affinities for each other such that a significant increase in signal is detectable/measurable upon interaction (e.g., binding) of the associated first and second entities. In some embodiments, one or both (or more) peptide/dipeptide/tripeptide tags have sufficiently low affinity for the other peptide tag and/or the polypeptide component that only background luminescence is detected in the absence of the interaction (e.g., binding) between the associated first and second entities. In other embodiments, the peptide/dipeptide/tripeptide tags and polypeptide component will form a complex and produce a signal in the absence of interaction between the associated first and second entities, but the signal is increased (e.g., 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, 10²-fold, 10³-fold, 10⁴-fold, 10⁵-fold, 10⁶-fold, or more or ranges there between) upon interaction (e.g., binding) of the associated first and second entities.

In embodiments in which a co-localization is being monitored/detected, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are selected that have affinities for each other, such that a signal from the luminescent complex is detectable/measurable even in the absence of an interaction (e.g., binding) of the associated first and second entities. In such embodiments, if the associated first and second entities co-localize (e.g., in the same tissue, in the same cell, in the same subcellular compartment, etc.), the peptide/dipeptide/tripeptide tags and polypeptide component will form a complex and emit a signal (in the presence of coelenterazine or a coelenterazine analog), whether or not the first and second entities interact with each other. In some embodiments, two or more (e.g., both, all) of the peptide/dipeptide/tripeptide tags have sufficiently high affinity for the other components that luminescence is detected in the absence of the interaction (e.g., binding) between the associated first and second entities. In some embodiments, no significant increase in signal is detected upon interaction of the first and second entities. In other embodiments, the peptide/dipeptide/tripeptide tags and polypeptide component will form a complex and produce a signal in the absence of interaction between the associated first and second entities, but the signal is increased (e.g., 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, 10²-fold, 10³-fold, 10⁴-fold, 10⁵-fold, 10⁶-fold, or more or ranges there between) upon interaction (e.g., binding) of the associated first and second entities.

In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) having known characteristics (e.g., spectral characteristics, mutual affinity, etc.) are used to elucidate the affinity of, or understand the interaction of, an interaction pair of interest. In other embodiments, a well-characterized interaction pair is used to determine the characteristics (e.g., spectral characteristics, mutual affinity, etc.) of one or more elements of a set of peptide/dipeptide/tripeptide tags and a polypeptide component. In some embodiments, peptide/dipeptide/tripeptide tags and a polypeptide component having known characteristics (e.g., spectral characteristics, mutual affinity, etc.) are used to characterize/monitor the co-localization of a co-localization par of interest (e.g., under desired conditions).

Embodiments described herein may find use in drug screening and/or drug development. For example, the interaction of a small molecule drug or an entire library of small molecules with a target protein of interest (e.g., therapeutic target) is monitored under one or more relevant conditions (e.g., physiological conditions, disease conditions, etc.). Such an assay may comprise a first peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) attached to a drug candidate (or a library of candidates) and a second peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) attached to a therapeutic target; luminescence in the present of the polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) and substrate indicates interaction and/or co-localization of the candidate and target.

Some embodiments herein find use in the diagnostic or criminal setting for monitoring for drugs (e.g., drugs of abuse in human) as well as for therapeutic drug monitoring of patients in biological samples. For example, two peptide/dipeptide/tripeptide tagged binding moieties (e.g., binding moieties separately tagged with peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) that recognize a drug analyte facilitate such embodiments. In some embodiments, a competitive dispalcement assay utilizing a peptide/dipeptide/tripeptide-tagged target in a system described herein to identify untagged target in a sample finds use in embodiments herein. Some embodiments find use in detecting environmental contamination, for example, soil samples, water supply, etc. being contaminated by a specific drug or other specific contaminant (e.g., small molecule contaminant).

In other embodiments, the ability of a drug (e.g., small molecule drug) or an entire library of drugs (e.g., small molecules) to enhance or inhibit the interactions between two entities (e.g., receptor and ligand, protein-protein, etc.) is assayed (e.g., by gain or loss of the bioluminescent signal). In some embodiments, drug screening applications are carried out in a high through-put format to allow for the detection of the binding of thousands, or tens of thousands, of different molecules to a target, or to test the effect of those molecules on the binding of other entities.

In some embodiments, provided herein is the detection of molecular interactions in living organisms (e.g., bacteria, yeast, eukaryotes, mammals, primates, human, etc.) and/or cells. In some embodiments, pep peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) fused to interaction (target) polypeptides are co-expressed in a cell or whole organism, and a signal is detected in the presence of a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) and substrate (e.g., coelenterazine or coelenterazine analog), wherein the signal is correlated to the formation of the interaction complex. In some embodiments, cells are transiently and/or stably transformed or transfected with vector(s) coding for fusions comprising peptide tags and interaction elements. In some embodiments, CRISPR is utilized to generate cells that express fusions comprising peptide/dipeptide/tripeptide tags and interaction elements. In some embodiments, fusions (e.g., of a cellular target and a peptide/dipeptide/tripeptide or polypeptide described herein) generated by CRISPR replace endogenous protein (e.g., non-fused cellular target) and are regulated in a similar manner to endogenous protein. In some embodiments, such endogenous taging is used to monitor the level of the endogenously tagged protein, especially in complex systems such as live cells, whole organisms, etc. In some embodiments, transgenic organisms are generated that code for the necessary fusions (e.g., fusions comprising peptide tags and interaction elements) for carrying out the assays described herein. In other embodiments, vectors are injected into whole organisms.

In some embodiments, provided herein is the detection of molecular co-localization in living organisms (e.g., bacteria, yeast, eukaryotes, mammals, primates, human, etc.) and/or cells. In some embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) fused to co-localization (target) polypeptides are co-expressed in a cell or whole organism, and a signal is detected in the presence of a polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) and substrate (e.g., coelenterazine or coelenterazine analog), wherein the signal is correlated to the co-localization of the co-localization elements. In some embodiments, cells are transiently and/or stably transformed or transfected with vector(s) coding for fusions comprising peptide tags and co-localization elements. In some embodiments, CRISPR is utilized to generate cells that express fusions comprising peptide tags and co-localization elements. In some embodiments, transgenic organisms are generated that code for the necessary fusions (e.g., fusions comprising peptide tags and co-localization elements) for carrying out the assays described herein. In other embodiments, vectors are injected into whole organisms.

In certain embodiments, cells are engineered to express one or more peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof), polypeptide component (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide), or fusions thereof (e.g., with cellular targets) using gene transfer technology or other engineering techniques. For example, the cells may be genetically engineered to express one or more peptide/dipeptide/tripeptide tags, polypeptide components, or fusions thereof (e.g., with cellular targets) using gene editing methodologies such as CRISPR (clustered regularly interspaced short palindromic repeat). The terms “CRISPR” or “CRISPR-Cas9,” as used herein, refer to the various CRISPR-Cas9 and -CPF1 (and other) systems that can be programmed to target specific stretches of a genome and to edit DNA at precise locations. CRISPR-Cas9 gene editing systems are based on the RNA-guided Cas9 nuclease from the type II prokaryotic clustered regularly interspaced short palindromic repeats (CRISPR) adaptive immune system (see, e.g., Jinek et al., Science, 337: 816 (2012); Gasiunas et al, Proc. Natl. Acad. Set U.S.A., 109, E2579 (2012); Garneau et al., Nature, 468: 67 (2010); Deveau et al., Annu. Rev. Microbiol, 64: 475 (2010); Horvath and Barrangou, Science, 327: 167 (2010); Makarova et al., Nat. Rev. Microbiol., 9, 467 (2011); Bhaya et al., Annu. Rev. Genet., 45, 273 (2011); and Cong et al., Science, 339: 819-823 (2013); herein incorporated by reference in their entireties). CRISPR gene editing systems have been developed to enable targeted modifications to a specific gene of interest in eukaryotic cells (see, e.g., Cong et al., supra; Xiao-Jie et al., J. Med. Genet., 52(5): 289-96 (2015); U.S. Pat. No. 8,697,359; Xie et al., Genome Res., 24(9): 1526-1533 (2014); Huang et al., Stem Cells, 33(5): 1470-1479 (2015); Smith et al., Molecular Therapy, 23(3): 570-577 (2015); and U.S. Patent Application Publication 2014/0068797; herein incorporated by reference in their entireties). Methods for utilizing CRISPR technology for gene editing are described in, for example, Barrangou et al., Science 315, 1709-1712 (2007); Bolotin et al., Microbiology, 151, 2551-2561 (2005); Brouns et al., Science 321, 960-964 (2008); Cong et al., supra; Deltcheva et al., Nature 471, 602-607 (2011); Gasiunas et al., supra; Hale et al., Cell 139, 945-956 (2009); Jinek et al., Science 337, 816-821 (2012); Makarova et al., Biology Direct 2006, 1:7 (2006); Mali et al., Science 339, 823-826 (2013); Marraffini et al., Science 322, 1843-1845 (2008); Mojica et al., J Mol Evol 60, 174-182 (2005); Pourcel et al., Microbiology 151, 653-663 (2005); and Sapranauskas et al., Nucl. Acids Res. 39, gkr606-gkr9282 (2011); herein incorporated by reference in their entireties.

In some embodiments, one or more peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) are employed as a protein tag (e.g., within cells, within a whole animal). In such embodiments, the complement components to the peptide/dipeptide/tripeptide tag(s) (e.g., polypeptide components, the other peptide/dipeptide/tripeptide tag, substrate) are applied to the system (e.g., cells, animal, etc.) (e.g., as part of a reagent) to detect/quantify the presence of tagged proteins.

In some embodiments, the small size of the peptide tags herein (e.g., β9-like (e.g., SmTrip9) and β10-like (e.g., SmTrip10) peptides) is useful for protein tagging.

In some embodiments, the components of the bioluminescent complexes herein (e.g., peptide/dipeptide/tripeptide tags herein (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof), polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are stable enough to exist in a suitable buffer for extended periods of time (e.g., in the presence of coelenterazine or a coelenterazine analog (e.g., furimazine) substrate). In certain embodiments, components of the bioluminescent complexes herein (e.g., peptide/dipeptide/tripeptide tags, polypeptide components, etc.) exhibit minimal detectable luminescence in the absence of the complementing components (e.g., even in the presence of coelenterazine or coelenterazine analog (e.g., furimazine) substrate). In some embodiments, optimized buffer conditions are utilized to meet criteria necessary for protein tagging.

The compositions and methods provided herein, as well as any techniques or technologies based thereon find use in a variety of applications and fields.

Provided herein are methods for the design and/or optimization of peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide), and the bioluminescent complexes that form therefrom. Any suitable method for the design of non-luminescent pairs/groups that are consistent with embodiments described herein, and/or panels thereof, is within the scope herein. In some embodiments, characteristics of peptide/dipeptide/tripeptide tags and polypeptide components, and combinations thereof are optimized by substitutions (e.g., substitution of natural amino acids, non-natural amino acids, amino acid analogs, etc.); such characteristics include, but are not limited to structural stability (e.g., of the peptide/dipeptide/tripeptide tag or polypeptide component, of a complex, etc.), expression, stickiness (e.g., to tubes, wells, etc.), brightness (or complexes formed therefrom), affinity for other components of the bioluminescent complex, solubility, thermal and chemical stability, low autoluminescence, etc.

In certain embodiments, peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and a polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are designed de novo to lack luminescence individually and exhibit luminescence upon association. In such embodiments, the strength of the interaction between the non-luminescent elements is insufficient to produce a bioluminescent signal in the absence of interaction elements to facilitate formation of the bioluminescent complex. In other embodiments, peptide/dipeptide/tripeptide tags and polypeptide components and/or bioluminescent complexes thereof are rationally designed, for example, using a bioluminescent protein as a starting point. For example, such methods may comprise: (a) aligning the sequences of three or more related proteins; (b) determining a consensus sequence for the related proteins; (c) providing fragments (e.g., one or more peptides/dipeptides/tripeptides and a polypeptide) of a bioluminescent protein that is related to the ones from which the consensus sequence was determined, wherein the fragments are individually substantially non-luminescent but exhibit luminescence upon interaction of the fragments; and (d) testing the fragments for the absence of luminescence when unassociated and luminescence upon association of the non-luminescent pair. In some embodiments, the fragments are mutated at one or more positions (e.g., in vitro, in silico, etc.), wherein said mutations alter the sequences of the fragments and result in optimization of characteristics.

In some embodiments, a peptide/dipeptide/tripeptide tag is a ‘dark peptide,’ or one that forms a complex with the other peptide tag and polypeptide components (e.g., with low or high affinity), but produces minimal or no luminescence. In some embodiments, a high affinity dark peptide/dipeptide/tripeptide finds use in inverse complementation or gain of signal assays for biosensors or for measuring inhibitors. In some embodiments, a low affinity dark peptide/dipeptide/tripeptide is used to bring down background luminescence of a complex for the detection of binding of a high affinity bright peptide/dipeptide/tripeptide tag to the complex.

In some embodiments, a peptide/dipeptide/tripeptide tag is a ‘quencher peptide,’ or one that contains a quencher moiety (e.g., DAB), and the quencher absorbs the light/energy produced by either or both of a polypeptide component (e.g., the signal produced independent of a complementing peptide/dipeptide/tripeptide tags) and/or bioluminescent complex.

In some embodiments, the luminescent complexes herein find use in systems, methods, assays, devices, etc. that utilize BRET between the complex and a fluorophore (e.g., small molecule fluorophore, fluorescent protein (e.g., cyOFP)). In some embodiments, a fluorophore (e.g., small molecule fluorophore, fluorescent protein (e.g., cyOFP)) is linked or fused to an analyte, cellular target, etc. In some embodiments, a fluorophore (e.g., small molecule fluorophore, fluorescent protein (e.g., cyOFP)) is linked or fused to a peptide/dipeptide/tripeptide tag and/or polypeptide component. In some embodiments, energy is transferred from a bioluminescent complex to an energy acceptor. In certain embodiments, an energy acceptor is a fluorophore or other detectable chromophore. Suitable fluorophores include, but are not limited to: xanthene derivatives (e.g., fluorescein, rhodamine, Oregon green, eosin, Texas red, etc.), cyanine derivatives (e.g., cyanine, indocarbocyanine, oxacarbocyanine, thiacarbocyanine, merocyanine, etc.), naphthalene derivatives (e.g., dansyl and prodan derivatives), oxadiazole derivatives (e.g., pyridyloxazole, nitrobenzoxadiazole, benzoxadiazole, etc.), pyrene derivatives (e.g., cascade blue), oxazine derivatives (e.g., Nile red, Nile blue, cresyl violet, oxazine 170, etc.), acridine derivatives (e.g., proflavin, acridine orange, acridine yellow, etc.), arylmethine derivatives (e.g., auramine, crystal violet, malachite green, etc.), tetrapyrrole derivatives (e.g., porphin, phtalocyanine, bilirubin, etc.), CF dye (Biotium), BODIPY (Invitrogen), ALEXA FLOUR (Invitrogen), DYLIGHT FLUOR (Thermo Scientific, Pierce), ATTO and TRACY (Sigma Aldrich), FluoProbes (Interchim), DY and MEGASTOKES (Dyomics), SULFO CY dyes (CYANDYE, LLC), SETAU AND SQUARE DYES (SETA BioMedicals), QUASAR and CAL FLUOR dyes (Biosearch Technologies), SURELIGHT DYES (APC, RPE, PerCP, Phycobilisomes)(Columbia Biosciences), APC, APCXL, RPE, BPE (Phyco-Biotech), autofluorescent proteins (e.g., YFP, RFP, mCherry, mKate), quantum dot nanocrystals, etc. In some embodiments, a fluorophore is a rhodamine analog (e.g., carboxy rhodamine analog), such as those described in U.S. patent application Ser. No. 13/682,589, herein incorporated by reference in its entirety. In some embodiments, a fluorophore is a small molecule fluorophore; embodiments herein reciting a fluorophore may be read as or limited to a small molecule fluorophore. In some embodiments, a fluorophore is a fluorescent protein (e.g., cyOFP, GFP, CFP, etc.; embodiments herein reciting a fluorophore may be read as or limited to a fluorescent protein (e.g., cyOFP, GFP, CFP, etc.).

In various embodiments, the bioluminescent complexes described herein, and components thereof, find use in a variety of different immunoassay concepts. For example, in some embodiments, a peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) is tethered/fused to a primary or secondary antibody to provide a method of detection for a particular analyte. As another example, a peptide tag is tethered/fused to an antibody-binding protein (e.g., protein A or protein G) and used to detect a specific antibody bound to a particular analyte (e.g., wherein the analyte is bound to the complementary peptide tag). As another example, a peptide/dipeptide/tripeptide tag is tethered/fused to streptavidin and used to detect a specific biotinylated antibody bound to a particular analyte (e.g., wherein the analyte is bound to the complementary peptide tag). As yet another example, peptide/dipeptide/tripeptide tags are tethered/fused to primary and secondary antibodies, where the primary antibody recognizes a particular analyte, and the secondary antibody recognizes the primary antibody. As still another example, a peptide/dipeptide/tripeptide tag is tethered/fused to an analyte and used in a competitive sandwich ELISA format. A peptide/dipeptide/tripeptide tag is tethered/fused conjugated to an analyte may also be used to detect antibodies capable of binding the analyte.

Various embodiments herein find use in small molecule detection via immunoassay. Exemplary embodiments comprise the use of a small molecule directly (e.g., identical or similar to the target small molecule) labeled with a first peptide/dipeptide/tripeptide described herein and a binding moiety for the target small molecule fused or linked to a peptide/dipeptide/tripeptide described herein. In the presence of polypeptide component and substrate (e.g., coelenterazine or coelenterazine analog), a bioluminescent signal is produced by the system. When the system is exposed to a sample (e.g., biological sample, environmental sample, etc.), the bioluminescent signal will be reduced if the small molecule target is present in the sample (the labeled small molecule will be competed out of the complex allowing, in some cases, quantitation of the small molecule target). Alternative configurations for such assays are also within the scope herein. In some embodiments, the target small molecule is a toxin (e.g., mycotoxin, etc.), metabolite (e.g., amino acid, glucose molecule, fatty acid, nucleotide, cholesterol, steroid, etc.), vitamin (e.g., vitamin A, vitamin B1, vitamin B2, Vitamin B3, vitamin B5, vitamin B7, vitamin B9, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin H or vitamin K, etc.), coenzyme or cofactor (e.g., coenzyme A, coenzyme B, coenzyme M, coenzyme Q, cytidine triphosphate, acetyl coenzyme A, reduced nicotinamide adenine dinucleodtide (NADH), nicotinamide adenine (NAD+), nucleotide adenosine monophosphoate, nucleotide adenosine triphosphate, glutathione, heme, lipoamide, molybdopterin, 3′-phosphoadenosine-5′-phsphosulfate, pyrroloquinoline quinone, tetrahydrobiopterin, etc.), biomarker or antigen (e.g., erythropoietin (EPO), ferritin, folic acid, hemoglobin, alkaline phosphatase, transferrin, apolipoprotein E, CK, CKMB, parathyroid hormone, insulin, cholesteryl ester transfer protein (CETP), cytokines, cytochrome c, apolipoprotein AI, apolipoprotein AII, apolipoprotein BI, apolipoprotein B-100, apolipoprotein B48, apolipoprotein CII, apolipoprotein CIII, apolipoprotein E, triglycerides, HD cholesterol, LDL cholesterol, lecithin cholesterol acyltransferase, paraxonase, alanine aminotransferase (ALT), asparate transferase (AST), CEA, HER-2, bladder tumor antigen, thyroglobulin, alpha-fetoprotein, PSA, CA 125, CA 19.9, CA 15.3, leptin, prolactin, osteoponitin, CD 98, fascin, troponin I, CD20, HER2, CD33, EGFR, VEGFA, etc.), drug (cannabinoid (e.g., tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN), etc.), opioid (e.g., heroin, opium, fentanyl, etc.), stimulant (e.g., cocaine, amphetamine, methamphetamine, etc.), club drug (e.g., MDMA, flunitrazepam, gama-hydroxybutyrate, etc.), dissociative drug (e.g., ketamine, phencyclidine, salvia, dextromethorphan, etc.), hallucinogens (e.g., LSD, mescaline, psilocybin, etc.), etc.), explosive (e.g., 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), pentaerythritol tetranitrate (PETN), etc.), toxic chemical (e.g., tabun (GA), sarin (GB), soman (GD), cyclosarin (GF), 2-(dimethylamino)ethyl N,N-dimethylphosphoramidofluroidate (GV), VE, VG, VM, VP, VR, VS, or VX nerve agent), etc.

The systems and methods described herein find use in a wide variety of applications and formats. The following are non-exhaustive exemplary examples of methods and formats utilizing the systems described herein.

-   -   In some embodiments, provided herein are intracellular two         protein systems for dynamic protein-protein interaction analysis         with SmTrip peptide-labeled proteins expressed as fusions via         traditional transfection or endogenously tagged proteins via         CRISPR; LgTrip can be used as a detection reagent either by         co-transfection, of LgTrip, providing a stable cell line         expressing LgTrip, or providing LgTrip in the detection reagent         and adding it to lysed cells expressing SmTrip-labeled proteins.         (FIG. 51A).     -   In some embodiments, provided herein are intracellular three         protein systems for dynamic protein-protein interaction analysis         with SmTrip- and LgTrip-labeled proteins expressed as fusions         via traditional transfection or as endogenously-tagged proteins         generated via CRISPR (FIG. 51B).     -   In some embodiments, provided herein are target specific assays         to measure analyte X with binding moiety A and binding moiety B         (See Table A; purified genetic fusions or chemically conjugated         SmTrip9 or SmTrip10 peptide) for a gain of signal assay (e.g.         diagnostic test, non-cellular, etc.) (FIG. 51C).     -   In some embodiments, provided herein are target specific         competition assays for analyte measurement through loss of         signal (e.g. diagnostic test, noncellular, etc.) (FIG. 51D).         Such a system use a purified binding moiety A (e.g., purified         genetic fusion or chemically conjugated comprising synthetic         SmTrip9 or SmTrip10 peptide) that binds the tagged target         analyte to generate light in the presence of LgTrip and a         coelenterazine substrate or coelenterazine analog, which may be         provided as part of a detection reagent. In the presence of         sample analyte X, SmTrip9 or SmTrip10 peptide will compete with         the sample analyte X to cause a loss of signal specific to the         presence of the sample analyte in the sample and proportional to         the concentration of the analyte.     -   In some embodiments, two or three of the peptide tags         peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like,         β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g.,         SmTrip10) peptides, and/or dipeptides and tripeptides thereof)         and polypeptide components (e.g., β1-5-like, β1-6-like,         β1-7-like, β1-8-like (e.g., LgTrip) polypeptide) are linked (or         fused) to recognition elements for proximal, but non-overlapping         (mutually exclusive or distinct), epitopes on the same target         analyte. A signal generated from the luminescent complex (e.g.,         in the presence of a substrate) indicates the presence of the         target analyte.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in immunoassays or various formats.         Immunoassays employing the peptide/dipeptide/tripeptide tags and         polypeptide components herein are not limited to full length         antibodies and may also employ antibody fragments or         non-antibody binding moieties (e.g., DARPins, aptamers,         affimers, etc.). In an exemplary direct immunoassay (See, e.g.,         FIG. 51E), two monoclonal or recombinant antibodies (mAbs or         rAbs) against an analyte are labeled with β9-like (e.g.,         SmTrip9) and β10-like (e.g., SmTrip10) peptide tags; a         polypeptide component (e.g., β1-8-like (e.g., LgTrip)         polypeptide) of the luminescent complex is included as part of         detection reagent (e.g., with substrate). For an exemplary         indirect immunoassay (See, e.g., FIG. 51F), generic reagents         labeled with β9-like (e.g., SmTrip9) and β10-like (SmTrip10)         peptide tags are used in combination with any paired antibody         system specific to an analyte (e.g., mAb or rAb +Biotin-pAb,         Biotin-mAb, or Biotin-rAb etc.); a polypeptide component of the         luminescent complex is included as part of detection reagent         (e.g., with substrate). An exemplary competition direct         immunoassay (See, e.g., FIG. 51G) is provided by labeling one         antibody with a first peptide tag (β9- (e.g, SmTrip9) or         β10-like (e.g., SmTrip10) peptide) and labeling a analyte with a         second peptide tag (β10- (e.g., SmTrip10) or β9-like (e.g.,         SmTrip9) peptide); a polypeptide component (e.g., β1-8-like         (e.g., LgTrip) polypeptide) of the luminescent complex is         included as part of detection reagent (e.g., with substrate);         loss of signal indicates the presence of unlabeled target         analyte. To provide a competition indirect immunoassay (See,         e.g., FIG. 51H), one antibody is labeled with a first peptide         tag (β9-(e.g., SmTrip9) or β10-like (e.g., SmTrip10) peptide), a         generic binding reagent (e.g., streptavidin) is labeled with a         second peptide tag (β10-(e.g., SmTrip10) or β9-like (e.g.,         SmTrip9) peptide), and analyte is labeled with a binding moiety         for the generic binding reagent (e.g., biotin); a polypeptide         component of the luminescent complex is included as part of         detection reagent (e.g., with substrate); loss of signal         indicates the presence of unlabeled test analyte. Alternative         immunoassays utlizing other         peptide/dipeptide/tripeptide/polypeptide combinations described         herein are within the scope of the present invention.     -   In some embodiments, provided herein are homogeneous assays         using peptide/dipeptide/tripeptide tag-labelled (e.g., β6-like,         β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like         (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides         thereof) recognition elements with the polypeptide component         (e.g., β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) as component of a detection reagent (e.g., along         with a substrate for the luminescent complex).     -   In some embodiments, provided herein are homogeneous assays         utilizing peptide/dipeptide/tripeptide-tag-labelled (e.g.,         SmTrip9, SmTrip10, etc.) and/or polypeptide-component-labelled         (e.g., LgTrip variants) recognition elements.

In some embodiments, such lateral flow         assays allow multiplexed         detection/identification/characterization of analytes (e.g.,         pathogens). In some embodiments, lateral flow assays find use in         performing immunoassays described herein.         -   An exemplary multiplexed tripartite lateral flow assay for             the detection and identification of pathogens using             tripartite antibody fusions in a direct immunoassay is             depicted in FIG. 52. In this example, a set of monoclonal or             recombinant antibodies (mAbs or rAbs), each fused to a             peptide tag (e.g., β10-like (e.g., SmTrip10) peptides) are             added to a liquid sample, the sample is passed over a             detection window comprising a second set of mAbs or rAbs,             each fused to a peptide tag (e.g., β9-like (e.g., SmTrip9)             peptides), immobilized in lanes within the detection window,             and each recognizing a distinct epitope on the same target             as one of the mAbs or rAbs in the liquid sample. When the             liquid sample is passed through the detection window in the             presence of a polypeptide component and substrate (e.g.,             preloaded in the detection window, added with the sample,             added separately to the device, etc.), luminescence in a             particular lane indicates the binding of mAbs or rAbs to             separate epitopes on a target, and thereby provide for             detection and identification of the target. The above             described assay, and alternatives thereof utilizing the             systems and methods herein, may find use in providing             various detection panels (e.g., Respiratory Panel:             Streptococcus, Pseudomonas, Mycobacterium, Staphylococcus;             Urinary Tract Panel: E. Coli, Klebsiella, Enterobacter,             Streptococcus; Food Borne Panel: Shigella, Campylobacter,             Salmonella, E. Coli, Listeria; Waste Water Management:             Coliform panel; Panel for strain identification within one             type of bacteria; etc.), as well as for other applications             (e.g., toxin detection).         -   An exemplary multiplexed tripartite lateral flow assay for             the detection and identification of anti-viral antibodies,             e.g., for disease diagnosis, using tripartite antibody             fusions in a direct immunoassay is depicted in FIG. 53. In             this example, a sample is added to the lateral flow device             and allowed to flow into a conjugation zone (e.g., pad). The             conjugation zone comprises a generic antibody-binding agent             (e.g., Protein L), tethered or fused to a first peptide tag             (e.g., β10-like (e.g., SmTrip10) peptide). If antibodies are             present in the sample, they will be bound by the labeled             antibody-binding agent. A detection window of the device             comprises separate lanes, each comprising distinct             immobilized viral antigens tethered or fused to a second             peptide tag (e.g., β9-like (e.g., SmTrip9) peptide). As the             labeled antibody flows from the conjugation zone into the             detection window, the antibodies will bind to appropriate             antigens, binging the peptide tags into proximity and             producing a luminescent signal in the presence of the             polypeptide component and substrate (e.g., preloaded in the             detection window, added with the sample, added separately to             the device, etc.). Such a device and assay would allow             detection and discrimination of multiple viruses and viral             infections using a single device/assay. For example, Zika,             Dengue, and Chicungkunga could all be independently detected             using a single test.     -   In some embodiments, the details of the above lateral flow         assays are carried out in a plate-based format for solution         phase assay (e.g., with the binding moiety combinations in wells         provided with a map). In some embodiments, such an assay is         performed in a multiplexed dot blot/spot array assay format. In         some embodiments, any multiplexed assays described herein in a         particular format (e.g., lateral flow) may also be performed in         alterantive formats described herein or understood in the field         (e.g., dot blot, spot array, etc.).     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in aerosol-based detection         (e.g., (1) protease to lyse cells, (2) spray detection         reagents, (3) visualize to detect/quantify).     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use with isothermal amplification of         nucleic acids.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use with rapid cycling PCR detection of         nucleic acids.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in the detection of protein-protein         interaction (e.g., between 2 proteins, between 3 proteins,         etc.).     -   In some embodiments, analysis of the assays and methods         described herein is performed using stationary or portable         devices and readers, a luminometer plate reader or handheld         reader, smart phone camera or CCD camera, etc.     -   In some embodiments, analyte is detected/quantified via gain of         signal through recognition elements via luminometer or imaging         based techniques.     -   In some embodiments, analyte is detected/quantified measured via         loss of signal through competitive displacement via luminometer         or imaging based techniques.     -   In some embodiments, systems and methods herein allow for         multiple tags on each recognition element, either genetically or         through chemical conjugation, thereby providing signal         amplification by adding increasing stoichiometry of peptide tags         per recognition element.     -   In some embodiments, systems and methods herein find use in         detection of native proteins in heterogeneous solutions.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in nucleic acid detection, for         example, peptide-tagged complimentary recognition elements         hybridize to a nucleic acid target sequence in tandem.     -   In some embodiments, assays are provided herein for the         detection of an antibody (e.g., antibody as analyte). One such         assay is depicted in FIG. 54. A first peptide tag (e.g., β9-like         (e.g., SmTrip9) peptide) is fused or tethered to an         antibody-binding protein (e.g., Protein L) and a second peptide         tag (e.g., β10-like (e.g., SmTrip10) peptide) is fused or         tethered to the analyte that the antibody is specific to; a         polypeptide component (e.g., β1-8-like (e.g., LgTrip)         polypeptide) of the luminescent complex is included as part of         detection reagent (e.g., with substrate); presence of the         analyte specific antibody in a sample results in complex         formation and luminescence.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in FISH-like applications utilizing         bioluminescence or BRET for detection/quantification.     -   In some embodiments, the peptide/dipeptide/tripeptide tags         (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9),         and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in detection of nucleic acids         (e.g., single stranded and/or double stranded DNA and/or RNA)         via, for example amplification-free detection of nucleic acids.         For example, as depicted in FIG. 56, a pair of peptide         tag-labelled nucleic acid probes, when hybridized to nearby         locations on a nucleic acid target, will allow formation of a         luminescent complex, facilitated by complementation with the         nucleic acid target. Such and assay could be performed on a         solid surface, in solution, for a single nucleic acid target, or         multiplexed (e.g., using an array).     -   In some embodiments, peptide/dipeptide/tripeptide tags (e.g.,         β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or         β10-like (e.g., SmTrip10) peptides, and/or dipeptides and         tripeptides thereof) and polypeptide components (e.g.,         β1-5-like, β1-6-like, β1-7-like, β1-8-like (e.g., LgTrip)         polypeptide) herein find use in lab-on-chip and/or microfluidics         applications.     -   In some embodiments, systems and methods herein find use in         heterogeneous assays, such as, immunoassays (e.g., PCR         amplification combined with homogeneous immunoassay analysis).

In some embodiments, a peptide/dipeptide/tripeptide-based sensor is provided is which a chemical (e.g., removal of a blocking moiety) or enzymatic (e.g., proteolytic cleavage) event is required to render a peptide tag capable of bioluminescent complex formation. For example, a protease is required to cleave a blocked dipeptide (e.g., incapable of bioluminescent complex formation) into two non-blocked peptides capable of complementation. In some embodiments, the peptide/dipeptide/tripeptide tags (e.g., β6-like, β7-like, β8-like, β9-like (e.g., SmTrip9), and/or β10-like (e.g., SmTrip10) peptides, and/or dipeptides and tripeptides thereof) and polypeptide components (e.g., β1-5-like, β1-6-like, β1-7-like, 62 1-8-like (e.g., LgTrip) polypeptide) herein find use with bead-based assays, utilizing magnetic enrichment for increased assay sensitivity. One such assay is depicted in FIG. 55. In such an assay, a magnetic particle is conjugated to a first peptide tag (e.g., β9-like (e.g., SmTrip9) peptide) and to a first binding agent directed to a first epitope on an analyte; a non-magnetic particle (e.g., polystyrene particle) is conjugated to a second peptide tag (e.g., β10-like (e.g., SmTrip10) peptide) and to a second binding agent directed to the first epitope or a second epitope on an analyte. The beads are combined with a sample, along with a polypeptide component (e.g., β1-8-like (e.g., LgTrip) polypeptide) of the luminescent complex. Magnetic separation is used to capture the magnetic beads and any components of the sample or other reagents bound thereto. Luminescence of the magnetically-captured elements is then detected in the presence of substrate for the luminescent complex. If the analyte is present in the sample, both the magnetic and non-magnetic beads will be captured, resulting in the capture of the luminescent complex. In the absence of analyte, the non- magnetic beads will not be captured, and the luminescent complex will not be formed. The above applications and formats are exemplary and non-limiting. Other embodiments consistent with the description herein are within the scope of the present invention. Systems comprising and method utilizing peptides, dipeptides, and polypeptides bearing structural (although not necessarily sequence identity) and functional correlation to portions of NanoLuc® commercial luciferase and/or natural luciferase from Oplophorus gracilirostris, and bioluminescent complexes formed by complementation thereof, are described herein. In particualr, detailed description is provided of complementaion between β ₁₋₈-like (e.g., LgTrip) polypeptides and either β₉-like (e.g., SmTrip9) and β₁₀-like (e.g., SmTrip10) peptides or β_(9/10)-like dipeptides. However, embodiments herein are not limited to complementaion between β₁₋₈-like polypeptides (e.g., LgTrip) and β₉-like (e.g., SmTrip9) and β₁₀-like (e.g., SmTrip10) peptides or β_(9/10)-like dipeptides. In some embodiments, eptides, dipeptides, and polypeptides bearing structural (although not necessarily sequence identity) and functional correlation to portions of NanoLuc® commercial luciferase and/or natural luciferase from Oplophorus gracilirostris are provided. For example, also provided herein are systems and methods for complementation between a β₁₋₅-like polypeptide and β₆₋₁₀-like polypeptide; between a β₁₋₂-like dipeptide and β₃₋₁₀-like polypeptide; between a β₁-like peptide, β₂-like peptide and β₃₋₁₀-like polypeptide; between a β₇₋₈-like dipeptide and β_(9-10/1-6)-like polypeptide fusion; between a β₁₋₇-like polypeptide and β₈-like, β₉-like, and β₁₀-like peptides; and/or between a β₁₋₆-like polypeptide and β₇-like, β₈-like, β₉-like, and β₁₀-like peptides.

In some embodiments, the peptides, dipeptides, triprptides, and/or polypeptides herein find use in translocation assays. In some embodiments, a translocation assay is composed of two components: a complementary polypeptide sensor (e.g., LgBiT-based, LgTrip-based, etc.) and a peptide/dipeptide/tripeptide-tagged protein of interest (POI). A variety of LgBiT sensors were genrated that localize at specific cellular compartments such as plasma membrane, nucleus, mitochondria and endoplasmic reticulum (ER) (FIG. 152). These LgBiT sensors can be introduced to cells via transfection or establishment of stable cell lines. The POI is endogenously tagged with peptide/dipeptide/tripeptide complementary to the polypeptide (e.g., LgBiT) . Under stimuli, the POI translocates to a different cellular compartment where the polypeptide (e.g., LgBiT) sensor resides, complementation occurs leading to the assembly of peptide/polypeptide complex (e.g., HiBiT∩LgBiT) to yield luminescence signal (FIG. 153). Thus, the translocation activity of POI is quantitatively measured via luminescence output. Experiments conducted during development of embodiments of the translocation assay are described in Example 89.

As described further herein, translocation assays can be designed as part of a modular system that includes, for example, the following components: 1) Cell lines expressing HiBiT-tagged proteins from endogenous loci; and 2) a LgBiT localization sensor. This principal design allows for the correlation of a luminescent signal with the presence of the target protein at a specific cellular localization. The sensors can include localization-specific sequences fused to a LgBiT affinity variant, as well as to HaloTag® for validation and imaging of the target compartment. Localization-specific sequences can be short peptides that are derived from known protein cellular markers. In some embodiments, when short peptides are not specific enough to exclude the LgBiT sensor to the cellular compartment of choice, full length protein marker can be used to fuse to the sensor. DNA sequences encoding LgBiT localization sensors can be cloned into a circular double-stranded DNA plasmid, which can be delivered into HiBiT cell line. In some embodiments, the delivery method can be via lipid based transfection using Fugene HD transfection reagent, or via viral transduction using Lenti viral particles or BacMam. In some embodiments, when transfected/transduced, cells are treated by an agonist, and HiBiT-tagged protein translocates to the cellular compartment where LgBiT sensor resides; complementation occurs and produces luminescence. In some embodiment, the agonists are small molecules that stimulate translocation of the target protein.

Experimental EXAMPLE 1 Further Truncated Version of (LgBiT) is Activated by Peptide

The luminescence of LgBiT (background and in the presence of complementary SmTrip10 pep86)(SEQ ID NO: 15, 25) was compared with a further truncated polypeptide (LgTrip 2098, SEQ ID NO: 17) lacking both the β10 and β9 strands of the full-length luciferase (background and in the presence of complementary pep263 (SEQ. ID 35)) (FIG. 1).

E. coli KRX harboring LgBiT (SEQ ID NO: 11) or LgTrip 2098 (SEQ ID NO: 17) were grown for 20 h from a single colony in LB+amp (50 ug/mL) at 30° C. (275 rpm) in a volume of 50 mL. From these cultures, 100x dilutions were made into the same media and the cultures grown at 37C (275 rpm) for 3 h and then cooled to 25° C. before adding rhamnose (inducing agent for protein overexpression) to a final concentration of 0.2%. Cultures were then grown (induced) for 22 h at 25° C. (275 rpm) at which time cultures were harvested, and the resulting pellets stored at −20° C. until processing. To lyse cells, pellets were removed from −20° C., resuspended in 50 mL of PBS pH 7.2, and taken through 3 sequential freeze thaw cycles (−70° C. to 22° C.), centrifuged to produce soluble fractions, and then kept cold (on ice) until assaying. Lysates and peptide(s) (25 nm final concentration) were incubated together for 10 minutes at 25° C. prior to the addition of NanoGlo® reagent . After addition of reagent, plates were incubated for another 5 min at 35° C. and read over time to measure luminescence (RLU) using a Tecan Infinite F500 plate reader.

Experiments conducted during development of embodiments herein demonstrate that both LgBiT (SEQ ID NO: 11) and LgTrip 2098 (SEQ ID NO: 17) produce some background luminescence, but the level is much higher for LgBiT. Data shows that both LgBiT and LgTrip 2098 produce more luminescence in the presence of their respective complementary peptide. The magnitude of the gain in signal in the presence of peptide is greater for LgTrip 2098. These data demonstrate that the further truncated LgBiT (and with the A51G substitution) is activated by a single complementary peptide corresponding to the (310 and (39 beta strands that are absent from LgTrip 2098.

EXAMPLE 2 LgTrip 2098 is Activated by Pair of Separate β9 and β10-like peptides

The luminescence of LgTrip 2098 (SEQ ID NO: 31) was monitored over time in the presence of separate peptides corresponding to the β10 and β9 portions of the full-length luciferase (SmTrip10 pep86 (SEQ ID NO: 25) and SmTrip9 pep245) (SEQ ID NO: 23) (FIG. 2). Similar experimental protocols were used as in Example 1; however, a 10× concentrated lysate was used, Peptides SmTrip10 pep86 and SmTrip9 pep245 were used at 500 nM, and 0.001% Prionex added to reactions. Experiments conducted during development of embodiments herein demonstrate that LgTrip 2098 (SEQ ID NO: 31) is activated by the addition of SmTrip10 pep86 and SmTrip9 pep245. Controls with no peptides added or only one of the peptides added produced near the background of the plate reader.

A two-fold titration series was prepared for each, starting with 5M NaCl in 25 mM Tris pH 7.5+0.01% Tergitol. 10 uM furimazine was added to each sample of the titration series, and 5 ul of each enzyme or enzyme+pep263 (SEQ ID NO: 35) were combined with 45 ul of each substrate additive mixture. Plates were incubated for 3 minutes and then read on GMM+.

To test the effect of prolonged exposure to salt, each enzyme was diluted to 1 uM, and a two-fold titration series was prepared starting with 5M NaCl in 25 mM Tris pH 7.5+0.01% Tergitol. 2 ul of each enzyme was added to 198 ul of the NaCl titration (10 nM final of each enzyme). The “no” additive control was TBS+0.01% BSA+0.01% Tergitol. Samples were incubated for 26 hours. After incubation, samples were diluted 1:10,000 into TBS+0.01% BSA+0.01% Tergitol (10 ul in 990 two times). 4 uM pep263 (SEQ ID NO: 35) was added to LgTrip 2098 (SEQ ID NO: 31), LgTrip 3546 (SEQ ID NO: 51), and LgBiT (SEQ ID NO: 11) in the second dilution. 50 ul of each sample was combined with 50 ul of NanoGlo® buffer+50 uM Furimazine. Plates were incubated for 3 minutes and then read on GMM+.

EXAMPLE 21 Effect of Urea on Activity

Experiments were conducted during development of embodiments herein to determine the effect of urea concentration on the activity of NanoLuc® (SEQ ID NO: 3), LgBiT (SEQ ID NO: 11), LgTrip 2098 (SEQ ID NO: 31), and LgTrip 3546 (SEQ ID NO: 51) (FIG. 17).

To test activity in the presence of urea, each enzyme was diluted to 1 uM in TBS+0.01% BSA+0.01% Tergitol and further diluted to 2 nM in TBS+0.01% BSA+0.01% Tergitol. 4 uM of pep263 (SEQ ID NO: 35) was added to LgBiT (SEQ ID NO: 11), LgTrip 3546 (SEQ ID NO: 51), and LgTrip 2098 (SEQ ID NO: 31) and incubated for 30 minutes. A two-fold titration series was prepared for each, starting with 10M urea in 25 mM Tris pH 7.5+0.01% Tergitol. 10 uM furimazine was added to each sample of the titration series, and 5 ul of each enzyme or enzyme+pep263 (SEQ ID NO: 35) were combined with 45 ul of each substrate additive mixture. Plates were incubated for 3 minutes and then read on GMM+.

To test the effect of prolonged exposure to urea, each enzyme was diluted to 1uM, and a two-fold titration series was prepared starting with 10M urea in 25 mM Tris pH 7.5+0.01% Tergitol. 2 ul of each enzyme was added to 198 ul of the urea titration (10 nM final of each enzyme). The “no” additive control was TBS+0.01% BSA+0.01% Tergitol. Samples were incubated for 26 hours. After incubation, samples were diluted 1:10,000 into TBS+0.01% BSA+0.01% Tergitol (10 ul in 990 ul two times). 4 uM pep263 (SEQ ID NO: 35) was added to LgTrip 2098 (SEQ ID NO: 31), LgTrip 3546 (SEQ ID NO: 51), and LgBiT (SEQ ID NO: 11) in the second dilution. 50 ul of each sample was combined with 50 ul of NanoGlo® buffer+50 uM Furimazine. Plates were incubated for 3 minutes and then read on GMM+.

The results demonstrate that NanoLuc® and NanoBiT® are more susceptible to inactivation by urea compared to LgTrip 3546, while LgTrip 2098 is the least effected by urea. The exposure results demonstrate that LgTrip 3546, LgTrip 2098, and LgBiT regain activity upon prolonged treatment with urea indicating that activity of these polypeptide may be negatively affected by contaminating proteins, and that denaturation of these contaminants enhances activity.

EXAMPLE 22 Effect of pH on Activity

To test the effect of prolonged exposure varying pH, each enzyme was diluted to 1 uM in TBS+0.01% BSA+0.01% Tergitol, which was then diluted to 20 nM in each buffer. T=0 samples were mixed and then diluted 1:10 into 200 mM HEPES pH 7.5+0.01% BSA+0.01% Tergitol and stored at 4° C. T=8 samples were mixed and then diluted 1:10 into 200 mM HEPES pH 7.5+0.01% BSA+0.01% Tergitol store at 4° C. T=24 samples were mixed and then diluted 1:10 into 200 mM HEPES pH 7.5+0.01% BSA+0.01% Tergitol store at 4° C. To perform the assay, LgTrip and LgBiT were diluted 1:10 in TBS+0.01% BSA+0.01% Tergitol+4 uM SmTrip10 pep286 (SEQ ID NO: 35), and NanoLuc® was diluted into TBS+0.01% BSA+0.01% Tergitol. 40 ul of each sample was diluted with 40 ul of NanoGlo® buffer+40 uM furimazine, incubated for 3 minutes, and then read on GMM+.

The results indicate that LgTrip is resistant to a wide pH range.

EXAMPLE 23 Autoluminescence

Experiments were conducted during development of embodiments herein to compare the autoluminescence of LgBiT (SEQ ID NO: 11) and LgTrip 3546 (SEQ ID NO: 51). Each was diluted to 3 uM in DPBS+0.01% BSA. Three-fold serial dilutions were prepared of each in DPBS+0.01% BSA (300 ul to 700 ul) and placed in wells of a 96-well plate. The last row of the plate contained the furimazine controls (n=12). 50 ul of each titration (or controls) were combined with 50 ul of NanoGlo® buffer+50 uM furimazine, incubated for 3 minutes, and then read on GMM+. LgTrip (i.e., LgTrip 3546) exhibited significantly reduced autoluminescence compared to LgBiT (FIG. 19).

EXAMPLE 24 Complementation of LgTrip with β9/β10 Dipeptide

Experiments were conducted during development of embodiments herein to determine the capacity of a β9/β10 dipeptide (e.g., pep263) (SEQ ID NO: 35) to form a bioluminescent complex with either LgTrip 3546 (SEQ ID NO: 51) or LgBiT (SEQ ID NO: 11). The luminescence of such a complex was compared with the luminescence of complexes of LgTrip 3546 with β9/β10 dipeptide and LgBiT with either SmTrip10 pep86 (SmHiTrip; SEQ ID NO: 25) or the dipeptide, pep263 (SEQ ID NO: 35) (FIG. 20). SmTrip10 pep86 (SmHiTrip; SEQ ID NO: 25) and pep263 (SEQ ID NO: 35) were diluted to 2 nM in H₂O. A 3× dilution series was prepared of each peptide in TBS+0.01% BSA starting at 300 nM. Solutions of 200 nM LgTrip 3546 and LgBiT were prepared in NanoGlo® buffer+50 uM furimazine (NanoGlo® reagent). 50 ul of each titration were combined with 50 ul of each NanoGlo® reagent, and luminescence was read after a five minute incubation. Signal/background was calculated by dividing the amount of peptide dependent RLU by the background reading. Results demonstrate that the dipeptide has a K_(d)˜2-3× higher than HiBiT which accounts for lower RLU at low peptide concentration. The background of LgBiT decreases signal to background. RLU values for LgBiT/dipeptide and LgTrip/dipeptide were equal.

Results (FIG. 27)

SmTrip 9 peptide variants were titrated in the presence of constant SmTrip10 ep86 (SEQ ID 15) (FIG. 27a ), and then SmTrip10 pep86 was titrated in the presence of saturating amounts of each SmTrip9 variant peptide.

The experiments demonstrate that identity of the β9-like peptide (e.g., SmTrip9) can influence the affinity of the β10-like peptide (e.g., SmTrip10) for the polypeptide component. SmTrip9 pep293 (SEQ ID NO: 154) and SmTrip9 pep294 (SEQ ID NO: 155) sequences have overlap with the C-terminus of LgTrip 3546 (SEQ ID NO: 51) and show a decrease in affinity compared to SmTrip9 pep286 (SEQ ID NO: 37) (no overlap), but also decrease affinity of SmTrip10 pep86 (SmHiTrip; SEQ ID NO: 25) for LgTrip 3546. SmTrip9 pep298 (SEQ ID NO: 158) and SmTrip9 pep299 (SEQ ID NO: 159) sequences overlap with the C-terminus of LgTrip 3546 and the N-terminus of SmTrip10 pep86 (SmHiTrip; SEQ ID NO: 25) and decrease the affinity of SmTrip10 pep86 (HiBiT) for or LgTrip 3546.

A cleared lysate was prepared by centrifugation of 7,000 RPM for 10 minutes.

Purification of the strands using the MagneHis purification system: 300 ul μl of MagneHis resin (Promega) was added to each sample, and then samples mixed 20 times and placed on a magnetic stand. The supernatant was removed, and the resin was washed two times with column wash buffer. Samples were eluted in 600 ul of elution buffer.

EXAMPLE 73 Strand Removal Proteins with Various Combinations of Peptides

200 μl of OptiMEM+10% FBS was added to multiple wells of a multi-well plate. Peptide combinations were added to a final concentration of 10 μM with each to be assayed separately with each strand removal protein. Each strand removal protein was diluted to 20 nM (2 nM for LgTrip 3546) in OptiMEM+10% FBS. 20 μl of each strand removal peptide was added to the designated peptide combination, samples e mixed, and 45 μl aliquoted in triplicate into wells of a white assay plate (Costar 3600). After 15-minute incubation at RT, 5 μl of detection reagent (100 uM Fz (Promega LCS N205)) was added to each sample. Samples were placed on an orbital shaker for 30 seconds, and then luminescence was measured every 2 minutes for 1 hour. Luminescence is reported as peak height of the kinetic read. Background is OptiMEM+10% FBS+detection reagent.

As demonstrated in FIG. 137, there was no signal over background for strand removal proteins 7, 8, 9, 10 when added as separate peptides. Two of the three peptide combinations gave ˜2× signal over background ((8+9) dipeptide+7+10) or ((7+8)dipeptide+9+10). One of the 3 peptide combinations gave ˜10× signal over background (((9+10) dipeptide+7+8) The two dipeptide combination of (10+9)+(7+8) gave signal of ˜4.5 logs over background. It is likely that the peptide combinations that gave the greatest signal have the highest affinity. Lower affinity combinations could produce light in a facilitated complementation assay. FIG. 137D demonstrates that peptides with alternative split sites (e.g., mid beta strand) are capable of forming a biolumiunescent complex.

EXAMPLE 74 Strands 6, 7, 8, 9, or 10 Removal (Purification) From LgTrip 3546 Template

400 μl of OptiMEM+10% FBS was added to multiple wells of a deep well 96-well plate. Peptide combinations were added to a final concentration of 10 μM each peptide to be assayed separately with either ATG-3929 or LgTrip. The peptide solutions were then divided. To one of the peptide aliquots, 20 ul of either 20 nM ATG-3929 or 2 nM LgTrip was added to the designated peptide combination, samples mixed, and 45 μl of the +/− peptide samples aliquoted in triplicate into wells of a white assay plate (Costar 3600). After a 15-minute incubation at RT, 5 μl of detection reagent (100 uM Fz in OptiMEM+10% FBS (Promega LCS N205)) was added to each sample. Samples were placed on an orbital shaker for 5 minutes. Background for each sample is OptiMEM+10% FBS+peptide dilutions+detection reagent.

As demonstrated in FIG. 138, sample ATG-3929 with strands (9+10)+(7+8)+6 shows ˜2× signal over background. On the other hand, the sample with two peptides (6+7+8)+(9+10) showed ˜300× over background.

Note that spontaneous complementation is not visible for samples with more than 3 peptides. It is possible that the affinity is not high enough affinity of the peptides is not high enough to produce light. It is possible that if the peptides are brought together through facilitated complementation with a fusion partner that it would be possible to obtain signal.

DNA samples were then diluted serially into carrier DNA (10 ul to 90 μl in 100 ng/ul carrier DNA) Next 20 ul of each DNA dilution was added to 83 ul of OptiMEM. Samples were mixed and then 6.6 ul of Viafect transfection reagent was added to each sample. Samples were incubated for 20 minutes at RT and then 5 ul of transfection complex was added to 6 wells of cells for each FRB-FKBP orientation. Plates were then grown overnight at at 37° C. with CO₂. The next day Rapamycin (RAP) was added to 3 of the wells for each sample to a final concentration of 100 nM. Samples were placed on orbital shaker for 1 minute and then Incubated at 37C for 30 minutes. After incubation, 100 ul of NanoGlo+50 uM Fz was added to each sample (+RAP and −RAP) and then samples were placed on orbital shaker for 5 minutes. Luminescent measurements were acquired using a Glomax Discover luminometer. Fold response was calculated by dividing RLU values from the +RAP sample by the RLU values from the −RAP samples. Results are depicted I FIG. 139C-E. Dipeptide fusions that have lower affinity to LgTrip produce a greater fold response compared to samples with higher affinity.

EXAMPLE 76 Development of a Tripartite Quantitative Assay for Anti-TNFa Biologic Agents Using Tripartite Fusion Proteins

Infliximab (Remicade), Adalimumab (Humira), and Etanercept (Enbrel) are TNFa inhibitors that all bind human TNFa and also all contain a human IgG1 Fc. A quantitative assay was developed for all 3 TNFa inhibitors by expressing and purifying SmTrip9- or SmTrip10-protein G and TNFa fusion proteins which serve as the binding components to the TNFa inhibitor (FIG. 140). The Protein G fusion protein will bind to the conserved IgG1 Fc region of the TNFa inhibitor. The Inhibitor will bind to the TNFa fusion protein bringing the SmTrip9 and SmTrip10 into close proximity. In the presence of LgTrip, the bioluminescent complex will form creating the signal that is proportional to the amount of TNFa inhibitor present. All reporter tag configurations were tested with SmTrip9 or SmTrip10 expressed on the N- or C-terminal of Protein G and TNFa with either a 4gly-ser or 15gly-ser linker. The optimal pairing resulting from screening all orientations was SmTrip9-15gly/ser-protein G with TNFa-15gly/ser-SmTrip10.

EXAMPLE 82 Development of a Tripartite Quantitative Assay for anti-EGFR Biologic Agents Using Tripartite Fusion Proteins in a Cell-Based Assay

We developed a quantitative, cell-based assay for panitumumab and cetuximab representing a phase separation or surface chemistry like assay. Using purified SmTrip9-Protein G fusion proteins that will bind to the conserved human IgG Fc region of the EGFR inhibitor, the Inhibitor will bind to the SmTrip10-EGFR fusion protein that is expressed on the cell surface bringing the SmTrip9 and SmTrip10 into close proximity. In the presence of LgTrip, the bioluminescent complex will form creating the signal that is proportional to the amount of EGFR inhibitor present. All reporter tag configurations were tested with SmTrip9 or SmTrip10 expressed on the N- or C-terminal of protein G or on the N terminal of EGFR with either a 4gly-ser or 15gly-ser linker. The optimal pairing resulting from screening all orientations was SmTrip9-4gly/ser-protein G with EGFR-15gly/ser-SmTrip10.

EXAMPLE 87 Quantitation of Human IL-1beta Using NanoTrip™ Chemically Labeled-Paired Antibodies

Experiments were conducted during development of embodiments herein to demonstrate the use of paired monocloncal antibodies that have been chemically conjugated with NanoTrip™ peptides to quantitation human IL-1beta. This model system consists of two monoclonal mouse antibodies that recognize IL-1beta at different epitopes. HaloTag®-SmTrip9 pep521 (SEQ ID NO: 268) was chemically conjugated to one of the antibodies, and HaloTag®-SmTrip10 pep289 (SEQ ID NO: 150) was chemically conjugated to the other antibody. In the presence of IL-1beta, the two antibodies bind to the IL-1beta thus bringing the two tags in close proximity. Addition of LgTrip 3546 (SEQ ID NO: 51) completes the complementation, and a luminescent signal is generated.

HaloTag®-SmTrip9 and HaloTag®-SmTrip10 fusion proteins are expressed and purified. Anti-IL-1beta mouse monoclonal antibody clone 508A 4A2 (Thermo) is labeled with the HaloTag®-SmTrip9 pep521 (SEQ ID NO: 268) and anti-IL-1beta mouse monoclonal antibody clone 508A 7G8 (Thermo) is labeled with the HaloTag®-SmTrip10 pep289 (SEQ ID NO: 150).

EXAMPLE 89 Translocation Assay

HiBiT exhibits a very high affinity for the LgBiT polypeptide (K_(D)=1 nM) and other similar complementary polypeptides. The strong interaction between the two fragments would drive complementation without any stimuli (FIG. 154), which would be unsuitable for a translocation assay. A study was conducted to determine the optimal affinity between two components (e.g., peptide and polypeptide) of a translocation assays. The optimal affinity was found to be in the range of 280 nM to 1300 nM. A quadruple mutations in LgBiT (E11K/I44M/N135V/L150S), referred to as LgBiT*, reduces its interaction with HiBiT by 1000 fold (K_(D)=1296 nM), renderring the HiBiT/LgBiT* pair well-suited for a translocation assay. Two different translocation assays were designed and tested.

A membrane translocation assay was developed to measure PKCα translocation from cytosol to the plasma membrane under PMA stimulus. PKCα was endogenously tagged with HiBiT at the C-terminus in HeLa cells. The clones of edited cells were isolated, and the best clone with the highest luminescence signal was chosen to perform the assay. LgBiT*-membrane sensor was introduced to the clone using transfection method. Addition of PMA recruits PKCα-HiBiT to the plasma membrane, where HiBiT meets LgBiT* to produce light. Titration of PMA yielded 12- to 19-fold increase in response depending on the amount of LgBiT* transfected (FIG. 155).

A nuclear translocation assay was developed using measuring p65 movement from cytosol to the nucleus under TNFα stimulus. The nuclear translocation assay was set up similar to the membrane translocation assay. Specifically, p65 was endogenously tagged at the C-terminus in HeLa cells, and LgBiT*-nuclear sensor was introduced to p65-HiBiT cell line via transfection method. Treatment of TNFα promotes translocation of p65-HiBiT to the nucleus, where complementation occurs between HiBiT and LgBiT* to yield luminescence signal. Titration of TNFα resulted in 4-fold increase in response (FIG. 156A). The assay allows measurement of protein translocation in real time. As shown in FIG. 156B, it takes approximately 30 minutes for p65 to migrate to the nucleus upon stimulation of TNFα, which is consistent with findings in the literature.

EXAMPLE 129 Strand 9 Detector Polypeptides

A polypetide construct was prepared by placing a strand 10 sequence at the N-terminus of a LgTrip polypeptide. This configuration produces increased luminescence in the presence of strand 9 sequences. Experiments were conducted during development of embodiments herein to determine the limits of detection for the strand 9 peptides being tested (pep521 and pep840).

a) Strand 9 Detector Proteins with pep521 and pep840

Each strand 9 detector protein was diluted to 20 nM in TBS+0.01% BSA. A 3× dilution series of pep521 and pep840 was diluted in TBS+0.01% BSA starting at 20 uM. 50 ul of each enzyme dilution in duplicate was combined with 50 ul of each peptide titration and incubated for 10 minutes on a shaker for pre-equilibration. An assay buffer was prepared by diluting Nano-Glo Live Cell Substrate (Furimazine; Promega; N205) 30-fold into TBS+0.01% BSA, 100 ul added to each well, incubated for 5 minutes at RT, and luminescence then read on GMM+. The background reading was obtained from samples that contained no peptide.

FIG. 200 shows that all three strand 9 detector proteins bound more tightly to pep840 than to pep521.

b) Strand 9 Detector Proteins with pep840

Each strand 9 detector protein was diluted to 200 nM in TBS+0.01% BSA. A 3× dilution series of pep840 was diluted in TBS+0.01% BSA starting at 0.5 uM. 50 ul of each enzyme dilution in quadruplicate was combined with 50 ul of each peptide titration and incubated for 10 minutes on a shaker for pre-equilibration. An assay buffer was prepared by diluting Nano-Glo Live Cell Substrate (Furimazine; Promega; N205) 30-fold into TBS+0.01% BSA, 100 ul added to each well, incubated for 5 minutes at RT, and luminescence then read on GMM+. The background reading was obtained from samples that contained no peptide.

Regarding FIG. 20, the panel on the left shows a titration of Strand 9 peptide 840 in the presence of 50 nM of three strand 9 detector constructs. The panel on the right shows the background (no peptide 840) for each strand 9 detector and the signal to background ratio at 0.1 nM peptide 840 for each strand 9 detector.

EXAMPLE 130 Linker Test Series

a) Overnight cultures of circularly-permuted, strand 9 detector variants were diluted to 1:20 (150 ul to 3 ml) in LB+0.1% rhamnose+100 ug/ml ampicilin, grown for 4 hours at 37° C., and then lysed in PLB lysis buffer (0.3×PLB+25 mM HEPES pH 7.5) (500 ul of lysate to 4.5 ml of PLB lysis buffer). To assay, lysates were diluted 1:100 into TBS+0.01% BSA. A 3× dilution series of pep840 (strand 9) was prepared starting at 10 nM. 50 ul of each dilute lysate was combined with 50 ul of peptide titration and incubated for 20 minutes at RT on a shaker set at 600 rpm. 100 ul Nano-Glo® buffer+50 uM Furimazine was added to each well, and luminescence then read on GMM+. The linkers used for each construct tested were: ATG-4992, 8GS; ATG-5485, SGS; ATG-5486, 6GS; ATG-5487, 7GS; ATG-5488, 9GS; ATG-5489, LOGS; and ATG-5490, 11GS.

FIG. 202 shows that each clone, other than ATG-5485, which has a 5AA linker, produced similar luminescence to ATG-4992. The experiments demonstrate that linker length between strand 10, and LgTrip did not play a significant role in the detection of strand 9 sequences.

b) 8GS Linker (ATG-4992) vs. 11GS (ATG-5490) Linker

ATG-4992 and ATG-5490 proteins were purified using the MagneHis purification system. (Promega). Purified protein for 4992 and 5490 were diluted to 100 nM in CO₂ independent media+10% FBS. A 3-fold serial dilution of pep840 was prepared starting at 10 nM in Nano-Glo® buffer+50 uM furimazine(Promega N113). 50 ul of each enzyme dilution was combined in quadruplicate with 50 ul the peptide titration. Luminescence was measured over time on a GMM+luminometer.

FIG. 203 show the data plotted is from the 50-minute kinetic read and that 5490, which has the longer linker, provided 2-fold more luminescence over 4992.

EXAMPLE 131 Determination of Kd of ATG-4992 and ATG-5490 Variants

Overnight cultures of each variant were prepared in LB+100 ug/ml ampicillin. The following day, cultures were diluted 1:20 (150 ul to 3 ml) in LB+0.1% Rhamnose+100 ug/ml ampicillin. Cultures were grown for 4 hours at 37° C. and then lysed with PLB lysis buffer (0.3× PLB (Promega)+25 mM HEPES pH 7.5)(500 ul of lysate to 4.5 ml of PLB lysis buffer). To assay, lysates were diluted 1:100 into TBS+0.01% BSA. A 3× dilution series of strand 9 (pep840) was prepared starting at 40 uM. 50 ul of the titration series was combined with 50 ul of the each diluted lysate, incubated for 20 minutes at RT on orbital shaker set to 600 rpm, 100 ul of Nano-Glo® buffer+50 uM Furimazine (Promega; N113) added, and luminescence read on GMM+. Results are depicted in FIG. 204.

EXAMPLE 132 Comparison of ATG-4992 and ATG-5490 Variants

ATG-4992 and ATG-5490 variant proteins were purified using the MagneHis purification system. (Promega). Purified proteins were then diluted to 100 nM in CO₂ independent media+10% FBS. A 3-fold serial dilution of pep840 was prepared starting at 2 nM in Nano-Glo® buffer+50 uM furimazine(Promega N113). 50 ul of each enzyme dilution was combined in triplicate with 50 ul the peptide titration. Luminescence was measured every 5 minutes on a GMM+luminometer. Results are depicted in FIG. 205 as data plotted from the 60-minute timepoint and show that variants 5515 and 5517 have lower calculated Kd values (Example 131) and show higher RLU signal to background values when paired with pep840.

Upon evacuation of the system, the lyophilization process was performed between shelf temperatures of −25° C. and +25° C. The ice sublimation phase lasted 8 hr, and the bound water desorption phase lasted 16 hr. At the end of the lyophilization process, the swabs were back filled with N° and sealed by inserting a second plastic swab jacket manually.

Swabs containing the lyophilized assay reagents were then rehydrated with 100 ul of nasopharyngeal swab samples +300 ul PBS containing 0.01% BSA. Total luminescence was measured on a handheld luminometer (Prom4ega) at times 15, 30, 45, and 60 minutes and plotted.

FIG. 216 show the results from 3 PCR confirmed negative (NS46, NS47, and NS52) and 3 PCR confirmed positive samples (PS46, PS49, and PS56).

EXAMPLE 140 Monomeric NanoBiT® with Fluoro-Fz

Each enzyme to be tested was diluted into TBS+0.01% BSA. A titration series with either Furimazine (N205) or JRW-1677 was made either TBS (start at 20 uM) or NanoGlo® buffer (start at 25 uM; Promega N112). Each substrate was serially diluted with either TBS+0.01% BSA or NanoGlo® buffer. 50 ul of each enzyme dilution as combined with 50 ul of each substrate titration. Plates were incubated for 3 minutes, and then luminescence measured on GMM+ luminometer. GraphPad Prism was used to generate a non-linear regression using Michaelis-Menten Least squares fit.

FIG. 217 provide the kinetic parameters (Vmax and Km) for Furimazine and JRW-1667. NanoLuc® (ATG-462) produced higher RLU values with both Furimazine and JRW-1667 (-10-20 fold) compared to the Monomeric NanoBiT® constructs when TBS is used to dilute substrates. NanoLuc® and the monomeric constructs showed similar RLU values in Furimazin/NanoGlo® buffer, but only NanoLuc® showed improved luminescence with JRW-1667. Although the monomeric NanoBiT® constructs showed lower RLU values with both Furimazine and JRW-1667, RLU values were similar for the two buffers and two substrates.

Km values were lower in TBS+0.01% BSA compared to NanoGlo, but generally the Km values were similar for each condition except ATG-3562 (Monomeric LgBiT-SmBiT), which shows a lower calculated Km for all conditions tested.
